DIY Aquarium Pump


Pomp for aquarium do it yourself

An aquarium pump is a water pump that pushes and pumps water. With this equipment, care for the aquarium. Making a pump for the aquarium with your own hands is not at all difficult. You just need to have on hand the necessary tools and materials.

How to make a pump for the aquarium with your own hands?

To make your own water pump for the aquarium, we need:

  • closed type container;
  • 3-5 V DC motor;
  • hot melt glue and a gun for it;
  • external power adapter (charging for mobile phone);
  • plastic rotor strips;
  • 2 plastic tubes (can be from a ballpoint pen);
  • scissors;
  • drill.

To extend the performance of the engine, you can first treat it with a WD-40 aerosol. Next, with a heated knife you need to make holes in the tank for plastic tubes. They should go in a couple of centimeters perpendicular to each other. From below we make a hole for the engine core. Glue the tube and motor.

The gear should fit under the engine pivot. From the pieces of plastic, make 4 blades for the rotor with a depth of 1.3 cm, glue them together. Glue the resulting part to the end of the engine core.

Close the airtight container cover, connect the charger wires to the motor.

It remains to connect the device to the mains and test it in action.

There is a kind of pump, as external. It is installed outside the aquarium. Making an external pump for the aquarium with your own hands is not at all difficult. For this you need a pump from the previous submersible filter, a cap with a net, a piece of foam rubber, a biofilter with a ceramic filler. The whole structure must be airtight, for which it is customary to use a tape-sealant or silicone glue.

External filter for aquarium do it yourself

What is an external filter for aquarium

There are two types of filters: external and internal. How to choose the one that fits exactly in your case?

First of all, pay attention to the size of your aquarium. If it is large enough, then there is not much difference. But usually we have only limited areas on which you can place either a small or medium aquarium. In this case, it will be appropriate to use an external filter.

Unlike the internal one, the external filter is not installed directly in the tank, but outside it. This helps to save space.

The external filter does not take place in the aquarium and does not spoil its overall appearance.

The work of such a device is as follows: water from the aquarium enters the device, passes through the filter elements, and then returns to the fish.

The external filter has the following advantages:

  • it does not occupy a useful place inside the aquarium;
  • the contents of the aquarium looks more aesthetic without such devices;
  • filtering fillers better purify water.

Of course, among the huge range of such devices, you can choose the right one for all parameters. But their prices are too high. So why not take the opportunity to make an external filter with your own hands? This project is easy to implement. It turns out that everything you need can be easily purchased in stores and on the market, and the assembly and installation work itself is simple enough for even a novice to cope with it.

How to care for the aquarium filter?

For the filter to work properly, it must be regularly clean. Otherwise, it will start to work worse, and after that it will completely pollute the aquatic environment (the latter concerns internal filters).

The smaller the filter area and the larger the volume of water, the more often it is necessary to clean the filter.

To determine the regularity of cleaning the filter, you should not only carefully read the manufacturer's instructions, but also watch the filter in operation. If it starts to work less, then it's time to wash it. Smaller filters may require weekly cleaning, and large models may require just one cleaning in 2 months.

In order not to destroy the colony of good bacteria, wash the filter with water at room temperature and do not do it too carefully. In addition, you should not wash the filter, if you change the water in the aquarium, add new fish, enter a new feed, otherwise you will break the established balance in the aquarium.

Washcloth replacement in the filter - another important point. Do not do this too often. Wait until it begins to lose its filtering ability and shape. In addition, the washcloth in the internal filter consists of several parts, and only one of them is needed at a time so that, later, beneficial bacteria from the “old” parts quickly spread to new ones.

Remember that the filter in the aquarium should work constantly and without interruptions, so take a responsible approach to the choice of a suitable model and do not chase the cheapest option. Stop the choice on the qualitative equipment which well proved itself and will serve you for a long time.

Homemade external filter for aquarium.

Being a lover of aquarium with a small experience, I came to the conclusion that the internal filter in my aquarium does not cope with its task. And from the frequent maintenance of the filter, only the inhabitants of my aquarium suffered.

After examining the information on the filters, I came to the conclusion that the unambiguous correct solution is to use an external filter. Biofiltration is extremely effective, and none of the methods of water purification can even partially replace it.

The composition of water purified by an external filter is approximately similar to water in slow-flowing natural water bodies. With a weekly refreshment of one third of the volume of the main aquarium, it can be assumed that the ichthyofauna and hydroflora are contained practically in flowing natural water - hence all the successes achieved in systems with biofiltration.

The news was not pleasant for me that the cost of the external filter turned out to be comparable with the cost of the aquarium itself.

After reviewing the design of externalists, I decided to make with my own hands an analogue of the external filter Eheim.

For the manufacture of homemade external filter were purchased:
- Pump (fountain pump), the company RESUN Chinese production 30 W., 2000 l / h.
- PVC coupling for sewer pipe d = 200 mm. + 2 plugs to it,
- cranes, corners, sgony, etc.,
- PVC pipe d = 20 mm. for receiving and supplying water to the aquarium 4 m.
- a flask from the household filter,
- Fillers for the filter.

For inserts in the plugs used fittings of the following design.

My choice on this pump was due to the fact that the filter has many bends in the tubes and the final performance eventually fell by half.

Drilled holes in the upper and lower cap for the supply and pumping of water. When installing fittings, I used rubber gaskets with an additional use of silicone-ion sealant.

I tried to insert the plugs into the clutch with sealing rubber bands and I did not succeed, it worked out too tightly. Understanding that if I succeed in inserting a stub, I will not pull it out from there. Proceeding from this, I cut the edges of the coupling in order to disassemble the filter, if anything, then it was possible to remove the gum and thereby depressurize the filter. At the bottom of the coupling made the seat under the inlet fitting.

A cut of the coupling edge will later be installed inside the coupling and will hold the grid.

In the lower cap installed grid above the level of the nozzle. For this we had to pull a box for vegetables.

After that, with a clear conscience, we can install the bottom cap in the coupling. Since the sealing gum will not be used here, it is necessary to coat the entire area of ​​the plug with silicone. And after installing the plug, we additionally coat the joints inside and outside with sealant.

In the lid additionally drilled a hole for the mains wire and air release. It was not necessary to fasten the pump to the plug, and even without this it is reliably fixed by the length of the hose and the mains wire.

For sealing the network wire used a fitting similar to that used in street lamps. In place of the wire break set the switch.

Under the inlet pipe set bracket for mounting the bulb of the household filter, which will serve as a preliminary filter for coarse cleaning. It would have been possible to do without it, but then I would have to install a sponge on the inlet pipe directly in the aquarium, or wash the canister every month (in my plans, washing the canister will take place at least once every 6 months).

For the manufacture of pre. filter needed PVC sewer pipe d = 32 mm. In which many holes were drilled. It would be possible to use, in addition, in before. filter activated carbon or zeolite, but first decided to do a foam sponge.

When all the details of the filter assembly proceed to filling with fillers.

1 layer. At the bottom in the first place we settle the material for coarse filtration. For these purposes, the most suitable foam with a large cell. But unfortunately I did not manage to find sheet foam rubber for aquariums of a suitable size. And instead he used something like a ball of fishing line.

2 layer. Fill with ceramic rings. The purpose of their use in the filter,, is to branch the flow of water and evenly distribute its current over the entire transverse area of ​​the filtering material.

3 layer. We put a layer of foam rubber with a small cell. In my case the synthetic winterizer was used.

4 layer. Fill with "bio balls" substrate for colonies of nitrifying bacteria. In this section all the mysteries of the nitrogen cycle take place. Here heterotrophs, nitrifiers, and denitrifiers peacefully coexist, regularly performing the duties assigned to them; the working volume of the chamber should be 4/5 of the biofilter body capacity. As a substrate for bacteria, claydite (preferably crushed) can be used because it has a porous structure.

5 layer. It is not necessary, but I decided to add the substrate FLUVAL. Externally, it looks like ceramic rings, only the material has a porous structure. If you take a ring into your hand, ring, plug a hole on one side with your finger, and blow it into the other on the other, then all the air will escape through the micropores.

6 layer. The final layer, directly in front of the exit intake hole (i.e. before the filter pump, one should place the synthetic winterizer. It will protect the rotor from dirt particles entering it.

Homemade external filter for the aquarium is ready, the assembly was successful. Testing showed a very good pump performance, although the pump performance was 2 times less. The top cover is not fully installed, due to the strong tight fixation of the sealing gum. If you close the lid to the end, it is possible that the filter will no longer open.

Filter maintenance is reduced to cleaning the pre-filter as it gets dirty. Opening and washing the cans in half a year. I want to note that it is necessary to wash in the filter only ceramics and foam rubber and always aquarium water. The extract is washed only as needed.

The first time after launching a homemade external filter actually works only as a mechanical one. Beneficial bacteria have not yet colonized the substrate. Dirt fills the filter, which causes a decrease in its performance. The water pressure gradually decreases. But there is a reverse process. Dirt is food for bacteria. They break down the organic matter that accumulates here and is processed into nitrate, i.e. begins biological self-cleaning filter.

Full colonization of the substrate by colonies of beneficial bacteria occurs within 2-4 weeks. And then it all depends on what process will take up - pollution or self-cleaning. If the first, the filter will continue to be contaminated. Not as intense as the first two weeks, but inevitable. When the filter performance drops below 30% of the maximum, it needs to be cleaned and restarted, otherwise a so-called can occur. "tipping" - a violation of biological processes, as a result of which poisonous substances are produced and thrown into the aquarium.

If self-cleaning gains the upper hand, the filter on the contrary is gradually freed from dirt and the performance that falls to 50-70% of the maximum is restored. Theoretically, after that the filter should work forever. In practice, productivity is not fully restored, and inside the canister, from time to time, stagnant zones are formed. Therefore, I recommend cleaning it from time to time, even if the water pressure is strong.

In addition, I want to note that all metal parts should be free from lubrication. Because a drop of oil can spoil a ton of water and thereby destroy all of your inhabitants. Therefore, it is desirable to use plastic parts (fittings, angles, taps), which in turn are much cheaper than metal parts.

P.S. Later, I replaced the hoses with corrugated ones (which are used to drain the washing machine), since PVC hoses easily crumpled and thus blocked the access of water.

The lid will need to be pulled off with pins, otherwise, if the light is turned off, it may be torn out.

Metal taps and fittings replaced by plastic which are used for irrigation.





DIY Aquarium Filter

One of the important elements in the equipment of aquariums is the filter. Many think first of all about which one to choose: external or internal. If you are going to draw a large amount, then the type does not matter. In other cases, it is better to use an external filter to save space. In specialized stores there is always ready-made equipment, but its cost is sometimes quite high. In this article, we offer to make an aquarium filter with your own hands.

How to make a filter with your own hands?

All the components that we will use to assemble the external filter with your own hands can be purchased on the construction market or in construction hypermarkets.

  1. First of all, we need quick-release garden fittings with a sealed lead-in. As well as a filter with different nozzles, plugs with sockets and sockets.)
  2. In the plug we make holes for fittings, sealed lead-ins and teats.
  3. We assemble the first part of the external aquarium filter with our own hands: we install the fittings and the pressure seal with the nipples, and then fix all this with the help of silicone.
  4. Included with the filter is a special pump, it is also fastened through the adapter. The "head" of the design is ready.
  5. The next step in assembling the filter for the aquarium will be the inside. It consists of the upper filter, intermediate separators and the filter housing itself. As separators it is convenient to use ordinary kitchen nets for washing.
  6. Put a bell on the grid and draw its outlines with a marker. Cut out.
  7. We will use a capron saucer from a flower pot as the upper separator. We drill holes in it: one for the inlet and a lot of small ones around it.
  8. Install the workpiece in the socket, connect with the coupling and fix with silicone.
  9. We assemble the finished parts of the aquarium filter with your own hands. Attach the "head" to the pipe and the upper separator.
  10. Begin to fill the nozzle. The author of the lesson proposes to use the following scheme: a sintepon, a separator, then a bio-ball, again a separator and at the end foam rubber.
  11. Included filter has a special corner.
  12. We prepare the second cap as follows: along the edges with glue we attach rubber stoppers for medicine bubbles (similar materials can be used). Next, collect the filter.
  13. Now follows the assembly of connectors with male and female threads, and the installation of tubes. (photo 23)
  14. We assemble the fittings for the external filter with your own hands. As a rule, all the necessary details are included with the filter.
  15. We take any environmentally friendly tube and make holes in it to increase the indentation area. You will also need a suction net, a mosquito net (this will be a prefilter, you must twist it into a tube and insert it into the suction tube). The intake tube is put on the intake using a silicone gasket. A small piece of garden hose will do. Also in the kit must be a discharge socket, tap and corners. Even if you cannot find all this in the kit, there are exactly the same parts on the construction market.
  16. The arc connection for butt fittings is called "overflow". It can be made from any plastic tube or use an extension pipe of an Atman canister. The manufacturing process is simple: we fill the wet sand into the tube and slowly begin to bend it over the switched-on gas stove. As a result, you get the desired shape and the tube will not crack.
  17. Filter for aquarium do it yourself! He blows work no worse than the purchase, and will save a lot of money and space.
