How to make a filter for the aquarium

maintenance, care, compatibility

Each aquarium should have a filtration system that will purify the water, ensuring the health of the fish and plants. As it is known, wastes that are left behind by the inhabitants of the reservoir, as well as the remnants of food, suspended particles of soil are very harmful for fish.

Not eaten feed is oxidized, turning into toxic ammonia. In order for the water to pass through all the steps of cleaning in a timely manner, it is better to make an external filter for the aquarium with your own hands.

It will prevent the appearance of harmful substances that can poison living beings.

The self-made external filter is constructed on the basis of aerolifting: air bubbles that come from the compressor, rise to the tube, from which they come to the top, and lower with them the water flow from the filter. Clean and oxygenated water enters the upper compartment of the glass, and passes through the gravel. Then the water enters the bowl through the hole, goes down the tube, and enters the tank.

Synthon here functions as a mechanical filter. This material prevents the silting of the gravel substrate.

External filters chemically and mechanically purify water. It is better to install such structures in a large aquarium with a volume of 200-400 liters.

For more spacious aquariums with a capacity of 500-1000 liters will need several such devices. Branded external water treatment systems are expensive, so it’s best to do it yourself.

Materials are inexpensive and accessible to everyone.



How to make a glass external filter for the aquarium?

To build an external filter, you will have to do it yourself, but without the help of specialists for some parts of the aquarium, this is not enough. It is about ordering a glass structure with partitions under the filter steps.

We will lay the filling in small containers, and the hull design depends on their size. Such cases will be manufactured where the aquariums are made to order.

  1. So, in the photo we see four compartments. The first three for the filter fillers, the last will be preliminary before the water enters the aquarium, there we will install a water heater and fill the water with oxygen.
  2. This is what those containers look like.
  3. For our self-made external filter for the aquarium, we need fillers of different fractions, many really need to prepare their own hands. Our goal is something like claydite and small fractions of different rocks, like granite and silicon. The largest particles will filter such ceramic rings. Well, the last stage of cleaning will be either a filler from the finished filter, or clean coarse sand.
  4. With all this we fill our containers and ship them to the glass compartments of the case.
  5. From the old filter, we take the detail of attaching it to the pipe. All containers are laid in their places, in the last compartment the heater and aerator are already installed.
  6. Next, we make a small stand so that the filter is slightly above the level of the aquarium.
  7. And here is the result of the work. The entire system is installed behind the aquarium and its inhabitants are provided with the necessary conditions of detention.

Filter for aquarium do it yourself. How to build a filter for the aquarium: schemes, tips

A good filtering device will never be cheap. What to do?

How to save? In this case, we advise you to make the simplest filter for the aquarium with your own hands.

To make it you will need: a sponge (you choose its size depending on the capacity of the aquarium), a nebulizer, a suction cup, a rubber tube, two 20 ml syringes, a small compressor.

Take one syringe. In one part of it, in which the medicine should be taken, make holes with a heated awl.

You need to connect the second syringe with the first one. This can be done with spikes.

To do this, hold the widest ends on the hot plate for a bit, quickly connect them and hold for 5-7 seconds. Cut from both ends the part into which the needle should be inserted.

You should have a long plastic pipe.

Take a sponge, make in one of its sides not a wide, but deep incision, insert into it a part of a syringe with holes. Get into the resulting “tube” rubber tube, connect it to the compressor. Attach a suction cup to one side of the syringe.

It will be attached to your filter to the wall of the aquarium.

How to install a filter in an aquarium?

So, you bought or made a filter for the aquarium with your own hands. Now what?

How to install it? What rules should be followed?

First of all, everyone should understand that in no case should a filter be installed in an empty aquarium. The container should be at least half filled with water.

It is also worth noting that before you assemble the filter for the aquarium, all the details of this device must be carefully dried. And only after that, proceed to install it.

The filter is usually attached to the wall with suction cups at a distance of 3 cm from the surface and in such a way that it does not touch the bottom. First, it must be submerged in the water off.

The tube that takes in air must be brought out. It is very convenient if a fastening is provided for this tube.

In a fixed state, it will not move and fall into the water.

If you understand how to install the filter in the aquarium, and did it correctly, then only now it can be plugged into an outlet. If the filter began to circulate and saturate the water with oxygen, then you should have no doubt that you did something wrong.

Filter for aquarium do it yourself :: DIY aquarium filters :: Household :: Other

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.

Now you can turn on the finished external filter and check it out in action.
