Do-it-yourself do-it-yourself automatic feeder circuit for an aquarium. Aquarium zoomir aquarium fish feeder

Why do people buy automatic feeders for their aquarium pets? The reasons are different: being very busy at work, the desire to ensure the exact implementation of the feeding regimen, leaving for a few days on business or on a trip, etc. It would seem that the easiest option is to go to the pet store and purchase it. But which feeder should you choose? Or maybe it makes sense to try to make it yourself?

What are the benefits of feeders?

A fish feeder is a kind of discipline. Feeding will be associated with only one place. Thanks to this, the condition of the water in the aquarium can be improved, since the residues will settle in only one place, which will allow them to be removed from the aquarium or collected by catfish. Catfish will not have to scour all over the ground in search of food, he will know exactly where to look for the treasured delicacy. The minimum distribution of food in the aquarium prevents decay processes, which means that the water stays clean longer.

The feeder for live food greatly facilitates the process of feeding. The fact is that the particles of such food are heavier than water and rapidly sink down, so sluggish fish or those who do not know how to eat from the bottom do not have time to enjoy live food to their fullest. Thanks to a properly selected feeder, the particles linger in it, which will allow the fish to slowly eat all the food offered.

Auto feeder: general principle of operation

The principle of operation of the device is based on the portioned supply of feed per unit of time. The mechanics of most modern automatic feeders is, in principle, the same: a strictly metered portion of feed is poured into the water through a hole in the drum.

After food is served, the drum rotates and its compartment is refilled from the common chamber. The capacity of the feed compartment is regulated by a special shutter, which can be moved in one direction or another until a characteristic click.

In addition to drum-type devices, there are:

Fully automatic feeders with the supply of feed during the opening of a special shutter (like curtains in old mechanical cameras).

As well as screw devices when the feed dose is adjusted by the number of turns of the worm shaft.

Also available for sale disk samples, where fish food is fed sequentially from compartments on the disk. At a certain time, the lower disk rotates, and all the food from one compartment is poured into the aquarium. The next drive bay is next.

But the main technological unit in all commercial automatic feeders is, of course, the electronic control unit.

Many devices can be powered by both household AC power and ordinary batteries.

How to make an automatic feeder for an aquarium?

The process of making a do-it-yourself automatic feeder is very simple and does not take much time. For work, we need the following materials:

small analog clock with alarm;
plastic transparent container;
transparent plastic tube with a diameter of about 7-8mm.

Now consider the instructions for making an automatic feeder for an aquarium with your own hands.

In a plastic container, we make a hole of a slightly smaller diameter than the cutting diameter, insert a tube. Then you do not have to use additional glue.

The drum does not need to be fully loaded. It is enough to fill it by two thirds, then the feed pellets will not fall out all at once under their own weight. In addition, the clock hand can withstand a certain weight and it should be loaded experimentally gradually, and we will attach the container to it.

How does a do-it-yourself fish feeder work?
The feed pellet container is attached to the clock hand. Since the container makes two revolutions in 24 hours, the granules will spill out of the hole in the tube twice a day. This is quite enough for feeding.
The size of the hole in the autofeeder tube, made by hand, will determine the number of pellets that will fall out at a time. The larger it is, the more food will get into the aquarium.
Do-it-yourself automatic feeder for an aquarium is ready and now it can be safely put into practice.

Choosing a place for the feeder in the aquarium

What will be used - an automatic fish feeder or a familiar one that requires manual manipulation, you choose. However, one rule should be remembered: carefully choose the place where you will have it, preferably where there is no aeration system and heating devices. Ideally, it is desirable to turn off the aeration system at the time of feeding, so that the feed does not spread over the entire surface of the water. However, as you understand, if an automatic fish feeder is used, this item may not be feasible.

Feeder Functions

Such designs are very useful when using live and dry food. It is they who do not allow food to spread over the entire surface of the water, getting into hard-to-reach places, where it will safely rot. In this regard, the automatic fish feeder is a real lifesaver. When using live food, the feeder is also very important. It allows you to keep heavy worms on the surface of the water, preventing them from getting lost under the stones at the bottom, where they are likely to rot.

In what cases can you do without an automatic feeder?

A working aquarist always has to solve the problem of regular feeding of his pets. Being away from home all day can be quite problematic. When you go on vacation for half a month, you can’t take an aquarium with you either, so such a lifesaver as an auto feeder comes to the rescue.

Nowadays, as it was done in the days of our grandparents, “reinventing the wheel” is not required, because, given the demand for automatic feeders for aquariums, some manufacturers of pet products have adopted them. These devices have a variety of designs and are programmed for hours of feed supply and its volume.

Brief overview of commercial designs

Like all other aquarium accessories, auto feeders from various manufacturers are quite widely represented in the distribution network. They differ in size, container capacity, device and, of course, price. Moreover, the cost depends mainly on the degree of automation: the more electronics in the feeder, the more expensive it is.

Model Eheim TWIN

The German company Eheim produces expensive, elite equipment for aquariums, and the samples of automatic fish feeders presented by this company are no exception.

It has 2 compartments for food with a total capacity of 160 ml. Each compartment operates independently, serving different types of food at different times. However, you can program the feeding process as you like.

To prevent the formation of product lumps due to moisture ingress, the device has a mini-fan that automatically dries the food in the compartments.

The model is powered by 4 AA batteries, which are included in the package; their resource is enough for about 4 months of work. Of course, the price of Eheim TWIN is rather big - about 7 thousand rubles for a 600-gram device.

Hagen (Hagen)

Another German company - Hagen - has taken the path of reducing the size of the equipment.

Thus, the Hagen Nutramatix electronic model weighs only 140 g, and its hopper holds much less feed - only 14 g.

This sample is well suited for feeding fry, as it can deliver doses of even the smallest dry food 2 times a day at the programmed time. The device runs on 2 batteries.

Juwel

The budget option of automatic feeders is offered by Juwel (Germany).

The drum-type model weighs 300 g, runs on 2 batteries, does not require labor-intensive maintenance and provides two feeds per day.

You can install the device anywhere, the main thing is to cut the appropriate hole in the lid of the aquarium.

This specimen has a hopper capacity of 100g and many aquarists believe that this device is almost ideal in conditions of their long absence.

FERPLAST CHEF

Italians do not lag behind German manufacturers.

The FERPLAST CHEF automatic feeder (screw type) accurately doses feed, can serve it 3 times a day, protects food from humid air and lasts quite a long time from 2 batteries.

In short, a variety of branded automatic fish feeders allows you to choose exactly the option that is needed at a given time. But you can make this device yourself.

Do not forget that aquarium fish are the same pets as dogs and cats. Like other pets, fish should have their own place to feed. Inexperienced aquarists are sure that the inhabitants of an artificial reservoir do not care how and where to eat. But, if we consider feeding through the feeder, it becomes clear that this method has many advantages. So, the fish get used to the place and time of feeding. The creation of a regime favorably affects the health of the inhabitants.

What are the benefits of feeders?

Variety of models

Today in the pet store you can find a huge assortment of different feeders for the aquarium. But if you do not want to spend money, you can build a simple structure yourself. All models can be divided into floating and automatic.

If you decide to purchase a floating version, it is more convenient to purchase a model with suction cups. Such feeders are attached to the wall, which will not allow the fish to move it, and carry the pump away. Most often there are plastic frames, in the middle of which food is poured. But if you still do not know where the power supply will be located, then you can choose the usual model without mounts.

Look out for live food feeders. In appearance, it looks like a cone, at the sharp end of which there is a mesh. The cone is conveniently located under water, so changing the height of the water will not affect convenience in any way. All the worms remain in the cone until the fish seizes them on its own. If you remove the grate from the bottom, you can use it as a regular feeder for different types of food. A fixed feeder on one of the walls of the aquarium is also not convenient due to the natural drop in the water level. If the feeder for the aquarium is fixed on one side, then after changing the level, the feeder will tilt and cease to perform its functions. Manufacturers have thought of this, so you can find modern floating models with guides that help it adjust to the water level.

Preference for automatic feeders is advised to people who:

Often on business trips or travel;
They contain a large number of aquariums.

The automatic fish feeder is attached to the upper edge of the side wall. It is a jar with an engine. The timer sets the time when food will be delivered to the pets. As soon as the time approaches the appointed time, the box automatically throws out the portion. Since the amount of food varies depending on the type and number of inhabitants, the feeder is equipped with a quantity regulator. To begin with, you will have to spend a lot of time to adjust the optimal amount. Remember that in no case should the food sink to the bottom and rot, no matter how hungry the fish look, it is worth limiting their diet.

An automatic feeder is ideal as the main source of food, but you should not let things take their course. After all, she is able to dose only dry food, and the fish need a balanced diet. Give the fish live or plant-based food.

It is necessary to install the feeder in the opposite direction from the filter and compressor. If you put it in the same corner, then the feed will simply be washed out of the feeder with a stream of water. So, the fish will remain hungry, and the food will spread in all directions.

How to make a feeder yourself?

Not everyone wants to buy a feeder, because you can make it yourself. For its manufacture, you can use:

Plastic,
Styrofoam,
rubber tube,
Plexiglas.

Making a styrofoam feeder is the easiest way. Even a child can cope with this task. Find a small piece of Styrofoam that will be 1 to 1.5 centimeters high. Decide on the optimal length and width of the feeding area and cut out a frame from the foam. It is advisable to walk along the edges with fine sandpaper to remove excess. Such a feeder has significant advantages: excellent buoyancy, ease of construction and low cost. However, there were some drawbacks - a short-lived design that easily absorbs odor and dirt.

Making a rubber tube feeder is even easier. It is enough to find a suitable tube with a diameter of 1 centimeter and glue the hollow ends together. It is important to do this very carefully, because if water gets into it, the ring will sink. Such a feeder is not afraid of mechanical damage and will last a long time.

For live food, it is better to use plastic and plexiglass. Take a piece of material up to 2 mm high. Make a frame of four strips, gluing them perpendicular to each other. Place a piece of plastic with drilled holes in the middle and glue it securely to the prepared frame.

Of course, the aesthetic side of homemade feeders remains in question. In addition, their cost in pet stores is not so high as to waste time on self-preparation of the necessary attribute.

We offer to profitably buy fish feeders for the aquarium and in the 12 Monkeys online store. We offer a wide range of models with different functionality.

Fish feeding devices not only make pet care easier, but also have an additional value:

They teach the fish to eat in one place - the food settles to the bottom under the feeder, which simplifies the removal of precipitation using a siphon.
Provide feeding mode - the automatic fish feeder in the aquarium allows you to feed at the same time. Scheduled feeding is good for fish health.
They allow you to accurately dose the feed - it is served in a given amount, which eliminates overfeeding, water pollution with residues.

The functionality of the aquarium fish feeder depends on the model.

Types of aquarium feeders

Manufacturers of aquarium accessories have developed a wide range of feeding equipment and accessories. Main types:

Electronic- a fish feeder for aquariums, powered by a battery or mains. The user adjusts the dosage and feeding time. Some models feed several times a day. Allows you to provide feeding in the absence of the owner - during holidays, work, business trips.
Mechanical– requires the participation of the user in the feeding process. For example, you need to press a button to rotate the feed drum, open the compartment.
Simple devices - cones, rings, sieves for manual feeding with dry and live food. They do not allow the food to spread on the surface of the water, stick to the walls of the aquarium, settle to the bottom. The advantage - these fish feeders are inexpensive - a budget option.

When choosing a model, you should pay attention to the characteristics:

Type of feed- granules, balls, dry fine mixture. Possibility of using frozen and live food.
The presence and volume of the feed compartment. Some automatic models are not equipped with compartments - you need to buy separately.
Equipment with suction cups and other types mounts, allowing you to fix the device on the wall of the aquarium.
Feeding method- superficial, bottom.

If you have any difficulties in choosing a model, you should consult with a specialist. Our range includes devices from leading manufacturers - Darell, Zoomir, Hydor, Sera, Hagen Tetra. Automatic models are reliably protected from splashes and moisture - food and electronics are prevented from getting wet.

The 12 Monkeys online store offers to buy automatic aquarium feeders, simple aquarium feeding equipment. Use the advantages - favorable prices, delivery methods to choose from, long-term guarantees.

A beautiful aquarium with graceful and elegant fish will decorate any room and give aesthetic pleasure to its owners. But sometimes people have difficulty with the timely feeding of pets. In this case, an automatic feeder for aquarium fish will help and save you from worries. Let's look at what models pet stores offer customers and how craftsmen can make an automatic feeder with their own hands.

Why you need an automatic feeder

In some cases, such a device can become simply irreplaceable.

For example:

the owner is at work 12 or more hours;
a vacation or business trip is coming;
young fish or a particularly capricious breed of fish requires frequent feeding.

Did you know? In Japan, imperial carps from the palace ponds were awarded to those who distinguished themselves as orders. If the recipient eventually fell into disgrace, the imperial fish could be taken away.

Do-it-yourself automatic fish feeder

Consider how to assemble an automatic feeder with an Arduino or any other microcontroller with your own hands. The device is made of a 5-volt 28BYJ-48 stepper motor in symbiosis with a real-time clock model DS1307.

A homemade feeder has the ability to serve fish food at a given time, distributing two types of feed at the same time.

Tools and materials

You will need:

Plexiglas 5 mm thick (1.5 square meters);
a bottle of Dichloroethane glue;

Important! The type of glue used for this design has a pronounced chemical smell and fumes that are harmful to health, so you need to dry the glued parts only in the open air.

hot glue;
fine sandpaper;
cosmetic cotton buds (for applying glue);
foil;
thin knife;
pencil;
drill 4 and 8 mm;
10 metal bolts with a diameter of 4 mm and 24 nuts of the same diameter (with a margin);
bolt and nut M6;
6 metal bolts and nuts with a diameter of 8 mm;
metal furniture corner;
metal hairpin M6;
aluminum tube (with a diameter suitable for the M6 stud);
plexiglass from the CD box;
electric jigsaw;
electric drill;
small metal vise;
screwdriver;
hand file.

Step by step manufacturing instructions

The order of work in the manufacture of automatic feeders is as follows:

Item #1- It is made of plexiglas 5 mm thick. Cut out a rectangle using a jigsaw. Approximate dimensions of this part: length 7.5 cm, width 4 cm, thickness 5 mm. The cut out rectangle is marked with a pencil. As a result of this marking, in the middle of the part, the contours of two future through holes in the form of rectangles (length 15 mm, width 10 mm) should be marked. The distance between these two holes is 15 mm. With an electric drill(section 8 mm) according to preliminary marking, several through holes are drilled located side by side, so that after refinement with an electric jigsaw, rectangular holes are obtained in these places, exactly corresponding to the previously drawn contours. Holes are also drilled at the corners of the quadrangular plate for future fastening of the part. The places where drilling will be carried out are moistened with water released from a disposable syringe. The resulting rectangular holes in the center of the plate are processed along the edges with a metal file to smooth out the burrs resulting from the drill. Finished part No. 1 is temporarily set aside.
Detail No. 1-a - 6 bars are cut from plexiglass: 7.5 cm long, 1 cm wide, 5 mm thick. The bars are glued to each other in threes using Dichloroethane glue. The glue is applied to the Plexiglas plate with a cosmetic cotton swab. As a result, after gluing, you will get two thick rectangular bars, the edges of which must be brought to absolute smoothness with a file and subsequent grinding with sandpaper. For the convenience of grinding with a file, glued sticks are placed in a bench vise, fixed on the edge of the desktop.
Item #2 - two more strips are cut out of plexiglass: length 15.5 cm, width 1 cm, thickness 5 mm. Between the two resulting strips, you need to glue the thick rectangular bars prepared earlier (part No. 1-a). Using a cotton swab, Dichloroethane glue is applied to the barrel of one of the bars and glued to the first Plexiglas strip. The second bar is also glued to it, placing it from the other end of the strip. An empty space of 5 mm is formed between two glued bars. After that, the upper sides of the glued bars are smeared with glue, and a second long strip of plexiglass is applied to them. For high-quality gluing, the structure is clamped in a vise for a time sufficient for the glue to set. To dry, the entire structure is taken out to the balcony.
Using a plate with rectangular holes in the center (part No. 1) as a stencil, mark all its holes with a pencil on a large sheet of plexiglass. Then using a drill with a diameter of 4 mm, side holes are drilled on a large sheet of plexiglass corresponding to each corner hole of the stencil plate. Next, a drill with a diameter of 8 mm is used, on a sheet of plexiglass they drill holes exactly in the middle between the two contours of rectangular through holes. 4 screws of suitable size are inserted into the resulting 4 mm holes and tightly fixed with nuts on the back of the plexiglass. One more nut is screwed onto the same screws so that there is a distance of 15 mm between the first and second nut. Part No. 1 is put on the legs of the screws, at the corners of which special holes are provided for this. To fix over part No. 1, one more nut is screwed onto the screws.
Item #3 - take an M6 bolt and nut and place it in a vise for ease of use. Hot-melt adhesive is applied to the nut in several layers, turning the bolt in the process of solidification. As a result, a through fastening is obtained, which is necessary for further assembly of the structure; it is connected into one piece with a metal corner. The factory hole in the metal corner is pre-drilled to a diameter of 7 mm. They bring the dried part No. 2 from the balcony and attach the finished part No. 3 to it with a screwdriver. A metal pin M6 is inserted into the hole located in part No. 3 (as a future axis of rotation).

Did you know? The Japanese eat puffer fish dishes with pleasure and amazing fearlessness. The liver of this fish carries a deadly poison, it is enough for the cook not to carefully remove the liver so that the poison penetrates into the meat. Although, in fairness, it should be noted that only specially trained people with a diploma are allowed to cook these dishes.

A coupling is made from an aluminum tube of suitable diameter. To do this, the tube is clamped in a vise and two holes are drilled through which a metal screw is threaded.
Using a screwdriver, a nut and a bolt, a 28BYJ-48 stepper motor is attached to a piece of plywood, a metal furniture corner is also attached there. All structural details are assembled on plywood and an emphasis is placed on the stud from a bolt fixed with a nut.
Next, food containers are made from the lid of a CD box.(it is made of rather thin plexiglass). To create one container, 4 pieces of plexiglass are cut in the form of truncated cones. There is no bottom in the container. Finished parts are fastened with adhesive tape or medical adhesive tape. The side edges of the parts (in assembled containers) are smeared with Dichloroethane glue, the glue is applied using cosmetic cotton swabs. For drying, glued containers are taken out to the balcony. Two food containers are made.
On the underside of a large plexiglass, to which all other parts are subsequently attached, glue foil. A self-adhesive dark film from a hardware store is glued onto the upper side of the same plexiglass. In places where there are holes drilled in plexiglass, foil and self-adhesive are pierced with a sharp knife. All parts of the feeder are assembled together at the top of a large plexiglass. Fish food containers are glued to part #1 directly above the rectangular through holes using hot glue.
A real-time clock module DS1307 is connected to the almost finished design.

Which automatic feeder for an aquarium to choose

The modern industry offers a fairly large range of automatic feeders for aquarium fish. Each of the models has its own advantages. We give a description of the most successful and easy-to-use structures.

Juwel

The automatic food dispenser Juwel EasyFeed feeds the fish in the aquarium without the presence of the owner, for example, during the holidays. The device is suitable for all aquariums and can be filled with pellets.
Juwel EasyFeed allows you to program up to two feedings per day.

The first feed is activated by switching on the feeder and is confirmed by a green LED. At this point, the fish will actually be fed and the time will be set to repeat the daily feeding cycle. If immediate feeding is required, it can be activated using the SET button.

The second feeding will take place 6 hours after the first feeding on all subsequent days. For example: activation of the device at 9 am, meals at 9 am and 3 pm.

By pressing the M button, manual feeds are always possible. The amount of food can be adjusted manually. You can also connect a Juwel automatic feeder to an air pump to keep the feed dry. The template holder (included) has a feeder cover that can be closed when the feeder is not in use and opens when required.
Model Features:

works with batteries, 2xType AA;
up to 2 feedings daily;
a 30-day supply container (60 servings);
the number of servings is adjustable;
there is a connector for an air pump;
dimensions: 13 cm x 6.5 cm x 7 cm (length x width x height);
suitable for all types of aquariums.

Did you know? Every year, millions of redfish swim into northern rivers to spawn. Fish cover distances of several thousand kilometers. At the end of spawning, all salmon dies, and the young that hatch from the eggs swim back into the sea only to return to their place of birth for spawning in the future and find death there.

Eheim

The Eheim Aquarium 3581 fish feeder is a single chamber fish feeder for aquariums. This device has a 100 ml loading chamber, which is mainly suitable for flake and granular products. The dosing opening is very finely adjustable.
At the largest opening, about 1 tablespoon of fish food is dispensed. Caution is advised with granulated feed: even the smallest opening will result in a rather large amount of feed falling out. The user needs to practice with the hole setting and feed interval to find the optimal settings.

Even mixing flakes and granules is very well accepted by the feeder and works great. Feed can be fed up to four times a day, up to a maximum of 2 feeds (equivalent to two rotations of the feeding chamber). By simply pressing a button, you can “eat” the fish at any time.

The peculiarity of Eheim aquarium feeders is that the feed chamber is actively ventilated and there is no sticking or mold of the fish food.

Did you know? To rest, fish also need to sleep. However, fish sleep with their eyes open, as they do not have eyelids. In addition, their sleep differs from human sleep in other ways: although their heart rate slows down, fish do not have deep phases of sleep. This dream is like a kind of twilight state, which can be immediately interrupted by the movement of water or the need to escape.

The Eheim aquarium fish device is easy to install and program thanks to the digital timer. The included bracket can be used to attach to open aquariums, including nano aquariums. The device fits all VARILUX aquarium covers. The function keys are splash-proof.

The device is powered by batteries, which are included in the purchased kit. It should be noted that the device does not work with rechargeable batteries. The device is well thought out: the warning system reports a decrease in battery power.

Resun

A handy aquarium feeder for vacations or business trips. It makes it possible to fill the container with feed without dismantling the automatic feeder. It is possible to select 4 different feeding modes within 24 hours, after which the device will automatically serve food to the fish four times a day. The RESUN automatic feeder regularly supplies the fish with food, so the owner can enjoy the holiday in peace, everything is in order at home.
The compact RESUN power supply is powered by batteries. With easy-to-understand programming, the owner decides when to invite the inhabitants of the aquarium "to the table." By simply pressing a button at any time, pets can be served "snacks".

The indication on the display promptly informs the owner that the battery charge has decreased. If the power supply is not recharged, the device automatically turns off after about 3 days. The final shutdown of the motor causes the opening of the drum to always freeze in the "up" position, so that the rising moist air in the aquarium does not reach the food.

The advantages of this design:

safe and convenient to use;
has automatic or manual feed;
simple programming;
daily feeding up to 4 times;
manual feeding (by pressing the button, the feeding process can be started manually at any time).

Did you know? The smallest fish on planet Earth is Paedocypris Progenetica, a member of the carp family. The fish lives in Sumatra, its body length is about 8 millimeters.

Trixie

This model of automatic fish food dispenser is ideal for pellets and flakes. Feeding occurs after 12 or 24 hours. The amount of food fed is automatically regulated, the fish food is protected from moisture absorption.
The manual setting is simple and clear, the auto-dispenser can be fixed on the lid of the aquarium or on the rim of the tank. The feed container is easy to fill and clean. The device is battery operated.

Features of this design:

ideal for granules and flakes;
feeding on 12- or 24-hour rhythms;
controlled amount of food;
fish food is protected from moisture;
feeding (between programmed meals) via instant manual adjustment;
convenient to fix on the lid of the aquarium or on the rim of the tank;
ease of use;
easy to fill;
easy to clean;
batteries are included.

Did you know? All clownfish are born male. If necessary, the largest male in the flock will turn into a female.

Sititek pet fish

The device dispenses feed doses up to 4 times a day. The automatic feeder can be programmed with 9 disposable portion sizes. The volume and supply of feed are flexibly adjustable, so the fish will not be hungry or overfed. Keeps feed crumbly and dry.
The device can be attached to the aquarium using clamps or suction cups. All operations can be quickly performed on the external LCD control panel.

Model Features:

flexible adjustment of the portion volume (from 0.75 to 6.75 ml);
feeder capacity - 215 ml (about 80 g of dry fish food);
the maximum number of days of automatic feeding is 99, the minimum is 1;
keeping feed dry;
daily feeding of fish - from 1 to 4 times a day;
the ability to switch to manual feed with automatic reminder;
battery low warning indicator;
powered by two AA batteries;
device dimensions: 150 x 95 x 58 mm.

Important! If the owner of the aquarium leaves the house for a long time, then, despite equipping the tank with an automatic feeder, it is advisable to ask good friends or relatives to visit the fish from time to time to make sure everything is in order.

Pets in the house limit the freedom of their owners, people cannot be away for a long time, as it becomes necessary to feed those for whom they are responsible in time.

Automatic fish feeders provide people with the opportunity to leave home for a few days and not worry about the remaining hungry pets. Whether to buy one of the automatic feeders offered by the industry or to make the desired design with one's own hand - only the owner of the aquarium can decide.

Auto feeders for fish: which one to choose?

Preparing this material for publication, I thought about how useful the information would be to the reader? Well, it’s clear that we all leave home: on business trips or on vacation. And often, it’s inconvenient for us to ask relatives to look after the aquariums, and besides, there are risks that the “looking rodya” will overfeed the fish, and even worse, screw something up ... But, in fact, the automatic fish feeders themselves are just a mechanism that is programmed for the issuance of feed in a certain period of time! What difference does it make what it will be?

Despite the fact that we live in an age of high technology and an abundance of consumer goods, it turns out that not everything is so simple! Each automatic feeder for fish has its own characteristics and nuances.

The main criteria that a fish feeder must meet are:

1. Easy and convenient to install. The feeder should be mounted in a place convenient for you, and not as the manufacturer intended. Its setting should not lead to a stupor.

2. The automatic feeder must be of high quality. Loaded feed should not stick together or deteriorate.

3. A fish feeder should provide for an abundance of operating modes. It should be suitable both for standard fish feeding and, for example, for frequent feeding when “raising” juvenile fish.
