Filtration system for multiple aquariums. Aquarium filters - the right choice

What is the best filter for an aquarium? This question is asked, perhaps, by every aquarist before buying an aquarium and fish. In this article, I will try to help you decide on this issue.

And so, first you need to decide on the volume of your jar, and those inhabitants who will live there. Since this issue will be decisive in choosing a filter for an aquarium. Decided, let's start choosing.

The first thing you need to pay attention to is, of course, the price of the filter and its power. Power is indicated on the packaging by manufacturers, and is measured in the abbreviation L / H, i.e. how many liters the filter passes through in one hour, for example 300L / H, this means that in one hour the filter distills 300 liters of water. Another parameter is the height h to which the water rises. I want to say right away that the data indicated by the manufacturer is always overestimated, since they are checked without the presence of a sponge or other filter media. In order not to be unfounded, I checked the pumps of two different manufacturers with a specified capacity of 1000L / H, in 1 minute one pumped 14 liters, the second 15. Having calculated how many liters per hour, we get that the first will pump 60x14 = 840 liters, the other 60x15 = 900 liters. The measurement was made with a clean sponge, with a dirty sponge it wakes up even less, i.e. the error is 10-16%.

I recommend choosing the power of the filter so that the filter pumps the entire volume of the aquarium an average of 7-10 times. Yes, sometimes manufacturers indicate this parameter on the packaging. But this is done mainly by the largest and most famous manufacturers. But the larger the volume of the aquarium, this parameter will vary. Below I will give an example of power selection.

200L/H = up to 30 liters;

300L/H = up to 40 liters;

360/H = 45 liters;

400-500L/H = 50-60 liters;

600-800L/H = 70-80 liters;

1000L/H = up to 100 liters;

1200L/H = up to 120 liters;

1500L/H = 150 liters;

2000L/H = 200 liters;

2500L/H = over 200 liters.

All filters are divided into types: internal, external, backpacks subspecies of external. Internal are divided into simple and bottom filters or false bottom. I emphasize that external filters produce quite a bit of noise, unlike internal ones, since in internal filters the noise is absorbed by the water inside the aquarium, although cheap ones without the NoName brand (purchased in online stores) produce them no less.

With performance, everything is clear, now let's deal with the principle of filtering. There are filters using the filtration method: mechanical, chemical, biological, combined, the most effective for large aquariums.

The most common mechanical filtration, the principle of collecting garbage, feed, feces, dead plants, suspension in one place on a sponge, synthetic winterizer or other filler is applied here. Sponges are finely porous for collecting small particles, and macroporous is used for coarse cleaning (large debris). They are used in simple filters in which the filter material is inside. Or frameless - this is a pump on which a sponge hangs. Both the first and second are located inside the aquarium.

Chemical involves filtration using adsorbents, activated carbon, and zeolite. These fillers absorb harmful compounds. Coal absorbs waste products, dyes, drugs, odors, chlorine. Zeolite fights ammonia, nitrites, nitrates, phosphate, stabilizes acidity. It is used both in internal and external closed filters together with or instead of a sponge.

Biological filtration is the most important used in conjunction with the first two, the purpose of which is to create colonies of aerobic and anaerobic bacteria breeding in substrates such as filter sponges, soil, unfired ceramics in the form of small tubes. These bacteria are involved in nitrification and decompose ammonia to nitrite and nitrite to nitrate. It is used in two three sectional internal filters or in external ones.

Combined includes the use of all the above described methods. As a rule, these are external large filters installed in cabinets under the aquarium (the most expensive filters). But they are also found in internal sectional rooms. Or backpacks that are hung on the walls of the aquarium from the outside.

And so, if you have a small aquarium up to 100 liters, it is quite enough for you to purchase a pump on the bottom to put unbaked ceramics in the form of decorations (cubes, tubes), or a housing internal filter with one or two sections, choose granular coal with zeolite as a filler. I recommend using Fluval Zeo-Carb filler, a mixture of zeolite and activated carbon.

Above 100 liters, it is desirable to use a combined filtration method using a pump and ceramic decoration for bacterial colonies, internal sectional filters with zeolite and granular carbon, or external filters using carbon, zeolite small ceramic tubes.

The final choice is up to you and your wallet.

This material is subjective, is not an advertisement and does not serve as a guide to the purchase. Before buying, you need to consult with a specialist.

An aquarium is a small artificial reservoir with a closed space, in which there are no processes of natural water purification from the waste products of the inhabitants. As a result, the water is polluted with waste, a population of small algae, pathogenic bacteria grows in it, and the environment becomes detrimental to the life of fish. Aquarium pumps are designed to solve the problem of purification, providing mechanical, chemical, biological water purification. Another one of them useful property- mixing of water flows. Thus, the environment is maintained in a qualitatively homogeneous state throughout the entire volume of the aquarium.

The filter is a container with a compressor and a cleaning filler, which is sponges, carbon components and other complex systems. According to the location of the device, they are divided into 2 types - internal and external.

Experts from the online magazine EXPERTOLOGY have chosen the best aquarium pumps in terms of performance and reviews in two categories: indoor and outdoor devices.

Rating of the best aquarium filters

The best internal filters for an aquarium

Indoor type devices are great for small aquariums with a small number of inhabitants. The filters are a compact plastic cylinder, inside which, in addition to the compressor, there are filter layers made of organic sponges and carbon.

If you have an aquarium, you need to keep it clean. Fish need clean and healthy water to live. Leftover food, fish waste and overgrown algae raise the pH level of the water, which is unsafe for the inhabitants of the aquarium. Exist various ways purification of aquarium water.

Steps

Aquarium installation

Don't rush to clear muddy water. It often happens that muddy water settles and brightens on its own. Often the water becomes cloudy due to the presence of various microorganisms in it, such as bacteria, protozoa and multicellular organisms. These microorganisms appear due to the presence of fish, food and waste from the inhabitants of the aquarium. Usually aquarium water reaches a normal state and is cleared in about a week.

Add beneficial bacteria to your water. Thus, you will improve the natural processes that take place in the aquarium. Beneficial bacteria can be added to an aquarium in two ways. You can buy a pack of bacteria or aquarium soil with bacteria already on it at a pet store. Can also be transferred from an old aquarium to a new one various items(pebbles, stones, wooden objects or filter pad) that already have beneficial bacteria on them.

Place suitable live plants in the aquarium. Another way to keep the water clean is to add live plants to the tank. Such plants are covered with beneficial bacteria, and they are also involved in the water purification process. They can be purchased at your nearest pet store.

Find out if you are using the correct filter. There are various filters that are designed for different purposes. The water may become cloudy due to the fact that you are using the wrong filter. The choice of filter depends on the number of fish and the type of aquarium, as well as whether it contains live or artificial plants.

• There are three types of aquarium filters. Mechanical filters remove particles from the water by forcing water through a material on which dirt particles settle. Biological filters use bacteria to convert toxic substances into less harmful ones. In chemical filters, toxins and harmful substances are removed from the water through chemical reactions.

1. Settle your aquarium wisely. Don't put too many fish in the tank as this can cause health problems and make it difficult to clean the tank. Try to have about four liters of water for every 2.5 centimeters of the length of the fish.

Turbid water treatment

Look for signs of bacterial blooms. After changes in the aquarium, such as changing large amounts of water, completely cleaning and treating the fish, bacterial blooms are possible. If this is what caused the cloudy water, you should be patient. After a few days, the bacterial balance will be established, after which the water should clear on its own.

Check filters. Water may become cloudy due to defective filters. The filter system contains bacteria that absorb waste products such as ammonia and purify the water. If the filters fail, bacteria can build up in the water, making it cloudy.

Adjust the aquarium for additional fish. If you have recently added a new fish to the aquarium, make the necessary changes. For example, if the new fish are larger than the old ones, this can be an unbearable burden for the filter system. In this case, change the filter system or reduce the number of fish in the aquarium.

Try not to overfeed your fish. Excess food can cause cloudy water. Fish need to be fed in moderation. Give them some food once a day and 1-2 days a week don't feed them at all.

Add decorations to the aquarium with care. Sometimes the water becomes cloudy due to the decorations. Before placing decorations in the aquarium, wash them thoroughly. Check all decorations to make sure they are suitable for your aquarium and are from a reputable pet store.

• Make sure that the decorations do not dissolve, disappear, soften, fall apart or change their color.

1. Control algae growth. Green algae develop on the walls of aquariums, and sometimes on decorations inside them. Algae can be scraped off during a scheduled water change. Using a soft plastic scraper, carefully remove the algae in one place, then rinse the tool and repeat the procedure. Rinse the scraper under a clean running water from the tap.

• In most cases, cloudy water clears up on its own. Just be patient.
• Do not overcrowd the aquarium with decorations, otherwise it will be difficult for you to clean it.
• When installing aquarium filters and pumps, follow the manufacturer's instructions.
• A general cleaning of the aquarium may be required, with the replacement of all water and cleaning of gravel, filters, decorations and walls. Undertake such cleaning only if other methods have not helped.
• Rotting organic matter often causes bacterial blooms and cloudy water. Check if all the inhabitants of the aquarium are alive and well.

Any person who breeds aquarium fish understands the need for water purification. Rivers and lakes are cleaned in a natural way, inapplicable in aquarism. Here it is customary to use artificial cleaning methods through a filter. The health of underwater inhabitants (fish, molluscs, crustaceans) and the growth of vegetation (echinodorus, anubias, ferns) depend on the cleanliness of the reservoir. We recommend choosing a filter that is small in size, easy to maintain and provides a highly efficient result.

On sale there are different models that create favorable conditions for the habitat of fish. They are internal and external. In order not to make a mistake with the purchase, you need to familiarize yourself with the pros and cons of a particular device. Treating the water and maintaining the right micro-environment will keep the fish in good health. The work of cleaning devices is aimed at removing contaminants that remain after uneaten or processed feed. The contaminated liquid passes through the filler and returns cleaned to the aquarium. Pressure and air flow balance the temperature and oxygen in the water.

The need for a filter in an aquarium

An aquarium requires special care and the use of certain equipment, in particular a filter. However, its installation is not mandatory if there are few fish in the tank. Experts believe that 10 liters of liquid is enough for one underwater inhabitant up to 5 cm in size. If these conditions are met, as well as timely garbage collection, water changes and aeration, a good environment without a filter is created. Aeration saturates the space with oxygen and oxidizes harmful trace elements. The dense population of the aquarium requires the mandatory installation of a filter.

Devices provide mechanical, biological and chemical filtration. The first cleans the walls of the tank with a sponge or a bundle of tangled fishing line that captures dirt and debris. This treatment is suitable for goldfish and cichlids. The biological method is carried out using live bacteria and special fillers. Such treatment removes toxic substances and waste products of fish and plants, and heals the environment. An effective chemical method is based on the absorbent action of activated carbon. Charcoal filler is able to absorb harmful impurities, remove ammonia, fetid odor.

Varieties of filters for the aquarium

As mentioned above, filters are either internal or external. The first models are budget. They provide only mechanical cleaning. Several options for simple devices are on sale: a foam rubber sponge fixed on an air diffuser, airlift, bottom. Some cleaning stations are equipped with additional options that expand their capabilities. Such devices are more expensive and offer complex treatment, provide heating, maintain a certain temperature, direct the water flow in a given direction, enrich it with oxygen and disinfect it.

Inexpensive indoor models are able to quickly clean the aquarium, are safe and easy to maintain, operate quietly, have an aerator, and are compact in size. However, they still reduce the area, do not perform chemical treatment, and have a short service life. The small volume of the cartridge requires frequent replacement. External or remote stations supply water using an airlift and a circulation pump and guarantee a high level of purification. They differ in functionality from the previous ones, do not take up space in the aquarium, are easy to clean, provide comprehensive washing and do not require frequent replacement of the cartridge. Noisy operation, bulky dimensions and high price are the disadvantages of such devices.

Buying a device is a purely individual matter, but when choosing, you should take into account a number of criteria: performance, reliability, design features, filtration methods, availability additional options, price. For densely populated domestic water bodies, in which, in addition to ordinary fish, there are inhabitants digging in the ground, cold-water or predatory fish, and there is also no dense vegetation, we advise you to buy a powerful filter that pumps a sufficient volume of liquid. Remember that a reliable device works continuously. Otherwise, in the absence of oxygen, beneficial microorganisms die, and anaerobic ones begin to release decay products, clogging the underwater space.

The capacity of the tank affects the choice of a particular model. Internal filters pass dirt through the sponge, which is replaced with a new one as it wears out. We recommend buying them for small aquariums. The remote device takes the contaminated liquid into a nearby canister, passes it through the filler and fills it back. Such models are suitable for larger domestic ponds or very small containers that do not have space for installing a submersible water purifier. Mounted appliances are not in demand due to design features. The filter located in the tank significantly reduces light exposure and contributes to weathering. carbon dioxide. For small aquariums, a bottom-mounted device is suitable, but it is characterized by low power and inconvenience in maintenance.

The disadvantage of the device is the expensive price.

The pump is powered by an electrical network with a voltage of 100 volts. To connect to a domestic outlet, a power convector of 220-100 Volts and a power of 100 watts is required! In case of non-compliance given condition the pump will fail!

Remote cleaning equipment provides high-quality processing, suitable for aquariums up to 500 liters. Contaminated water becomes clean by passing through five media: ceramic rings, biological balls, standard sponge, carbon and fiber pads. Filter baskets are equipped with handles for easy replacement of fillers. The drain tube and hose are adjustable to the size of the home tank. Installed valves adjust the flow of water in accordance with the wishes of the user. Before servicing, the valves are closed and the adapter is disconnected. The liquid remaining in the hoses allows not pumping when connecting the device. The pre-filter reduces the need for frequent maintenance. The filter material is replaced as it wears out or every six months.

EX-1200 Plus Pros:

• Doesn't flow;
• No noise;
• Does the job well.

After cleaning, the pump may not start the first time.

The water in the aquarium is the main environment for the life of fish. The health of the inhabitants, their appearance and activity depend on its quality. Aquarium water is polluted with food residues, secretions of fish and other animals, plant particles and even dust from the air.

Rice. 1 High-quality water purification in the aquarium is very important

A properly equipped aquarium should be a balanced system. Bacteria settle in it, which decompose harmful organic matter, do not allow algae to multiply excessively, but mechanical inclusions do not disappear anywhere. In addition, a densely populated aquarium does not always have time to self-clean. In this case, he needs help in the form of a biological water treatment plant. In all cases, filters are required to purify the water in the aquarium.

To remove all unnecessary components from aquarium water, several cleaning methods are used.

1. Mechanical filtration is the easiest way. With its help, mechanical inclusions of different sizes are retained, suspension is removed, food residues and dead parts of plants are removed. Mechanical cleaning is carried out using different filter materials. The most commonly used porous synthetic sponge. Suspensions linger in its pores. Periodically, the sponge is taken out and washed.
2. Biological filtration is a method of removing dissolved organic matter from aquarium water. This process is carried out with the help of bacteria. They settle on a special substrate, for example, on porous ceramics. As water passes through the ceramic, bacteria trap the organic matter and decompose it into simpler, more harmless substances.
3. Adsorption - not often used. Adsorption filters are used to quickly remove various substances from the aquarium water, such as medicines after treating fish. The most commonly used adsorbent is activated carbon.
4. Disinfection - performed using ultraviolet lamps, ozonizers or special chemicals. Use decontamination in quarantine aquariums or in preparation for launch. A properly functioning aquarium with an established equilibrium does not require decontamination. In addition, it eliminates not only harmful microorganisms, but also beneficial bacteria.

Varieties of aquarium filters

To use the methods of cleaning water in an aquarium, special devices have been created - filters. They are divided into two main groups depending on the place of installation: internal and external. The principle of operation of these filters is the same. The water is sucked in, passed through the filter media and released back into the aquarium. In addition to purification from pollution, oxygen saturation occurs.

The performance of the devices is selected depending on the volume of the aquarium. low power leads to the fact that the water is cleaned too slowly and the aquarium is gradually polluted. The filter does not have time to clean the entire volume before the appearance of new contaminants.

Too powerful unit is also not a good option. It will quickly pass the entire volume of water in the aquarium and eliminate all impurities, but at the same time it can suck up small fish and create a strong current.

Internal filter options

Internal aquarium filters are devices that are installed inside the aquarium. They are immersed in water and work directly in it. There are several types of indoor appliances.

The simplest design option is a device with an airlift. It works with the participation of a microcompressor, which is connected to the filter tube. Cleansing is carried out through a foam rubber sponge.

The internal filter with the built-in pump has the case in which there is a filler. Simple models perform only mechanical cleaning, while more complex ones have several compartments with different filter materials. They simultaneously clean from mechanical impurities and from organic matter, i.e. are biofilters.

Bottom filters are a special kind. This device is installed before filling the aquarium with water. The filter plates are laid on the bottom. They are covered with soil, and the pump with the motor is located at the surface. Water can be sucked through the ground and exit through the pump, or it can be reversed. In this case, the pump takes it, and the bottom plate releases it.

External aquarium filters

External filters are located outside the aquarium, which allows them to be made quite large. A larger volume of filler improves water purification. With the help of an external device, multi-stage purification of aquarium water can be carried out. Combining several types of filtering gives the best result.

Most often, external filters are biofilters. A substrate is laid inside them, on which bacteria settle. The larger the area of ​​the substrate, the large quantity bacteria settles on it and the higher the level of purification.

Typically, external filters are represented by canister models. They have a barrel-shaped body with an inlet and outlet hose. Through one, water is pumped into the device, and through the other it comes back.

External filters are used for large aquariums. The internal filters in them do not cope with cleaning or the installation of two devices at once is required. Via external filter in a large volume, an optimal environment is created.

Filters are selected based on several criteria. The first is required view filtration. Further attention is paid to the power and compliance with the volume of the aquarium. It will be useful to evaluate the noise and reliability. You can evaluate the reliability by the quality of the assembly of the product and by the manufacturer. The best quality German filters are provided, Polish ones are not bad, and purchasing a Chinese version is a certain risk.
