At the word “water pump”, many people immediately recall a complicated technical device that supplies compressed air for the operation of a pneumatic hammer in road construction. That is why when it comes to self-manufacturing aquarium water pump, it causes some confusion. Meanwhile, making a small device with your own hands for forcing air into the aquarium water is quite capable of almost anyone. But how to do it? And in general, why is it needed? Let’s try to figure it out.
What is air supply to the aquarium for?
Being a device for creating pressure (compression), the unit delivers air directly into the aquarium environment. This process is very important for the decorative flora and especially the fauna. Fish are known to breathe through the gills with oxygen dissolved in water. If there is little oxygen in it, the very existence of pets will be threatened.
In the domestic artificial reservoir, such air saturation is performed using aeration — forced, controlled supply of air flow into the aquarium water. Moreover, the smaller the air bubbles emerging from the water pump, the more dissolved air is formed in the water space.
One can say this: a water pump is an ordinary air pump.
The main types of professional aquarium water pumps
Manufacturers of different countries have developed a wide variety of aquarium air pumps that can satisfy any owner of ornamental fish. Structurally, the devices can be divided into 2 main types:
Piston professional water pumps are more powerful and are designed for aeration in large-capacity aquariums, over 200 liters, for example. At the same time they are the most noisy, since the movement of the piston is always accompanied by a rather loud sound.
Membrane Air pumps are almost noiseless, their work is based on the movement of a rubber membrane that pumps air into the outlet tube.
The price range of these technical devices is also quite wide – from several hundred to 20 thousand rubles (for example, the Italian pump Sicce MULTI), depending on the design, equipment, power and other characteristics.
air pump for aquarium do it yourself
Such a device can be assembled, if you understand the basic principle: first you need to somehow accumulate air, and then gradually submit it to the aquarium. This is the fundamental difference between an improvised unit and commercial piston or diaphragm pumps operating from an electric motor.
But how can you accumulate air? The answer suggests itself: in a balloon, car chamber, soccer ball camera, etc. By the way, it is the inflatable ball that some homemade craftsmen use in such cases.
So, in order to quickly and without special difficulties to assemble an aquarium inlet pump, you need:
- rubber chamber (like an air battery);
- car (or bicycle) pedal or hand pump;
- three-way faucet (tee);
- plastic tube from a medical dropper with a clip.
Three tubes should be taken from the tee: the first to the hand pump, the second to the inflatable ball, and the third tube (a dropper hose with a clip) will be the output hose. The end of this hose must be firmly plugged, and in front of it a tube must be punctured with several small holes, from which air will flow. Of course, all connections must be reliable and tight.
To collect air using a tee, the pump-chamber line opens first. The ball chamber is very durable in itself, so you can pump it up to failure. Then this direction is blocked and the “camera-outlet tube” line is turned on. In order for the air to enter the aquarium gradually, the diameter of the outlet tube in one place is regulated by means of a clamp. Naturally, this clip should be outside the aquarium, closer to the tee. Experienced way selects the flow rate of the air flow.
In principle, a homemade water pump is ready. The disadvantage of such a device is that the battery chamber must be periodically pumped. As a rule, for normal aeration of an aquarium with a capacity of up to 100 liters, such pumping should be carried out 2 times a day. Therefore, a homemade water pump cannot be left unattended for long.
DIY Aquarium Sprayer
It has already been mentioned that a larger number of small air bubbles have the best effect on the degree of oxygen saturation of water. This is achieved with the help of the so-called sprayer, which can also be made independently. Special knowledge and skills are not needed here.
First way: use of a short rubber tube that is put on the outlet hose. It is enough to pierce a set of holes with a needle from all sides of the tube, firmly plug its free end – and the sprayer is ready. By the way, such holes can be punctured on the air hose itself, but it is better not to spoil it and use a rubber spray nozzle.
There is another option. For example, a natural stone looks very impressive in an aquarium, from which a lot of air bubbles come out. For this fit myotis porous or porous limestone. But in this case, there are two problems. First, it is necessary to take into account the influence of the stone on the state of the rigidity of the aquarium aquatic environment. And secondly, it is necessary to ensure reliable fastening of the edge of the output air hose to the stone. In principle, a special silicone will help to successfully solve this problem.
You need to take a longer piece of rubber tube (almost equal to the length of the aquarium), and pierce the tiny holes in groups in several places at the same distance from each other. This tube can be placed on the bottom along the back wall and slightly decorated. Columns of air bubbles will rise from these areas, uniformly mixing water with oxygen. Yes, and looks like aeration is very attractive.
With the normal maintenance of ornamental fish and aquatic plants, the water pump is indispensable. Some advanced home craftsmen assemble such devices using standard electric motors, grind out the flywheel and pump parts on lathes, and place homemade devices in soundproof boxes. Of course, such technical home-made deservedly are the pride of their owners.
However, in all other cases, it will be easier and more reliable to purchase an inexpensive commercial water pump that, if properly used, will last a long time, providing pets with life-giving oxygen.
