Any aquarium needs filtering. Tiny particles of dirt, waste products of inhabitants, other organic matter tends to gradually decompose, releasing ammonia harmful to fish.

In order to avoid their poisoning, it is necessary to activate the processes that convert harmful substances into nitrates.

The question “How can you properly breed geese?” – 1 answer

Biofiltration aquarium – the conversion of ammonia to nitrite, and then into nitrates. This process takes place with the participation of beneficial bacteria in the aquarium and depends on the absorption of oxygen.

It is necessary to maintain a continuous stream of water enriched with oxygen in the aquarium, which is achieved using a filter.
You can purchase a filter for an aquarium at the store, but if the price seems excessive, it can also be made at home. The effectiveness of the work will depend on how attentive you are to its production.

To make a homemade biofilter for an aquarium, you need a bottle from under a half-liter carbonated water, a plastic tube of the same diameter as the inner diameter of the bottle neck, a piece of padding polyester, small pebbles with a fraction of no more than five millimeters, and a compressor with a hose.
The bottle should be carefully cut into two parts. One of them must be larger than the other to make a small bowl with a neck and a large bottom.

The cup is directed with the neck upwards and with an effort is pushed into the bottom so that it sits tightly there. On the outer circumference of the bowl you need to make a few holes through which water will flow into the filter.

It is better to make holes with a diameter of 3-4 mm, arrange them in two rows, 4-6 holes in one row. Insert the tube into the neck of the bowl so that it came in with a little effort. There should be no gaps between the pipe and the neck.

The tube length should be chosen in such a way that it protrudes slightly above the structure. At the same time, it should not rest against the bottom of the bottle so that the water would enter it freely.
Pour gravel over the bowl with a six-centimeter layer and cover it with a padding pad. Insert the aerator hose into the tube, fix.

When the whole structure is placed in the aquarium, turn on the compressor to start the filter. Beneficial bacteria will appear in the working filter, due to which ammonia in the aquarium will decompose into nitrates.

The design of the homemade filter is based on airlift. From the compressor air bubbles are fed into the tube, and from there they go upwards and at the same time draw water streams out of the filter. Fresh water enriched with oxygen enters the upper part of the glass and passes through a layer of gravel.

Then it goes through the holes made in the bowl, goes down and flows down the tube to the aquarium. The synthetic winterizer plays the role of a mechanical filter in the design – it is necessary to prevent silting of the gravel there.

External filter for aquarium makes chemical and mechanical water purification. Typically, this type filters installed on aquariums with a volume of 200 liters. Very large aquariums may require several filterov

These devices belong to a high price category, so you can try to make such filter do it yourself

1. Pick for enclosure filterand a cylindrical piece of plastic. For these purposes, a piece of plastic sewer pipe is suitable. The length of the pipe fragment must be at least half a meter.

The hull will require plastic parts that play the role of cover and bottom. Make a hole in the bottom of the case. Screw the fitting into this hole.

You can buy it ready or take it from another device, for example, from the sensor from the heating boiler of the bus. Then you will need FUM tape to seal the thread.

Wind it onto the threads of the fitting. Lock the fitting with the enclosed nut inside the housing. filterbut.

2. Cut a circle out of plastic. Using a drill or a knife, make a lot of medium-sized holes in it. Put a circle on the bottom filterbut.

Thanks to him, the bottom hole filterand will not be very clogged.

3. Getting Started filterOur filler. Put a round piece of foam rubber on top of the plastic circle. On top of the foam rubber, pour in a special filler for filterWater rations, which can be bought at a pet store.

It is made of ceramic material. Repeat layers again.

First foam and then ceramic biofilter.

4. Over filterLayers installed electric pump. It will create the movement of water from the bottom up. For a wire with a switch that goes from the pump, make a hole in the plastic case.

Insulate the hole sealant.

5. Prepare two tubes. They may be plastic.

With the help of them will be the flow of water in filter and its exit back to the aquarium. Connect one tube to the bottom outlet. To the bottom of the tube you need to connect a special faucet that will remove air from the external filterbut.

Connect another tube to the top cover. filterand to the fitting. Immerse the tubes in the aquarium.
