The main types of professional aquarium compressors

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 compressor, 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 compressor 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. Consequently, a homemade compressor can not be left unattended for a long time.

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.

If the “can” is low and long (there are such forms of aquariums), then the air should be sprayed in several places. Otherwise, all the fish will be collected in one place aeration.

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 water plants, a compressor cannot be dispensed with. 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 compressor, which, if properly used, will last a long time, providing pets with life-giving oxygen.

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.

Depending on the location of the pump in the aquarium, its functions may be different. The pumps differ from each other according to the installation method and are of three types:

The internal pump is installed in the aquarium, and it can only be used while being submerged, and the external pumps are attached outside the water tank. But most often, pumps make universal, they can be installed both inside and outside the tank with water.

For fixing the pump both inside and outside, various devices are used, for example, suction cups, special clamps and so on.

To choose the right pump, you must first know the volume of the aquarium, and also decide what the pump will be used for. If it is used to supply water to an aquarium and to create a flow in a small tank, then a low-power pump will be sufficient.

But for an aquarium with a volume of more than 250 liters you need a more powerful pump. There are pumps that are designed for both freshwater and marine aquariums.

And there are some pumps that are used only in one specific type of aquarium. Therefore, when buying a pump, you should clarify its type, for which aquarium it is needed, as well as the manufacturer of the pump. Some Russian pumps are not inferior in terms of workmanship and durability of foreign ones.

Buying a pump for the aquarium should not be saved, because the pump is one of the main life support systems for aquarium inhabitants.

In today’s market, buyers often come across devices from manufacturers such as Eheim, Aquael, Aquarium, etc. At Eheim, a water pump for an aquarium successfully copes with increased circulation of water, while the slider allows you to control the intensity of the generated water flow.

The main line produced by the company – This is Eheim Universal, Eheim Compact and Eheim Compact +. Most Eheim models are attached using suction cups and are considered versatile, as they can be attached both in the aquarium and on its outer wall. Their capacity is from 270 to 2280 l / h.

It will be possible to buy a submersible pump for an aquarium both for 1000 rubles (which capacity is 120-380 l / hour) and for 14,000 rubles with a capacity (2400 l / hour). The features of Eheim pumps can be considered: Small size; Suction mount; The possibility of complete immersion in water; Adjustment of pump power; Possibility of use in both salty and fresh water;

Protection of the inhabitants of the aquarium with a tread (intake grille); Stylish appearance; Built-in multifunctional filters. It is with such powerful systems that talented designers create a huge underwater realm, where air bubbles “draw” intricate shapes.

For small aquariums, where there is no need for expensive and powerful pumps, you can use cheaper pumps.

Everywhere common device under the brand name Hailea. Each pump for the aquarium of this brand is equipped with a water flow regulator, an innovative sump valve and a rubber suction cup.

Compared with expensive models from Eheim, they are less attractive in appearance, but at the same time, pumps of this brand successfully cope with their work, and therefore are actively bought up by people.

You can buy a water pump for an aquarium from this manufacturer already for 400-500 rubles, with a capacity of 180 l / hour. If you need the most powerful device – for 6000 rubles you can buy a device with a capacity of 7800 l / h.

Also known model brand Aquael. This is another representative of the budget class – prices for devices start at around 300 rubles. For this amount you can buy a model Aquael Circulator 350, capable of pumping up to 350 liters per hour, with a power of only 4.5 watts.

This is the “weakest” model – there are devices in the assortment of the manufacturer, labeled as Aquael Circulator 500, 650, 1000, 1500, 2000 and 2600. The number on the label, of course, indicates performance.

The price of the most powerful device is within 4500 rubles. Another well-known representative is Resun.

Models of this brand also belong to the budget – it is often chosen by amateurs who have small aquariums at home. The manufacturer has a huge range of devices – in the presence of more than two dozen items. The weakest and cheapest is the Resun SP 500.

It can pump up to 200 liters per hour, at a power of 5 watts.

Such a device costs only 300 rubles – one of the minimum indicators in its segment. Already for 600 rubles, this brand offers to buy a device with a capacity of 1380 liters.

The most powerful option – 12000 l / h: Resun Eco-Power EP-12000. There is such a device in the region of 6000 rubles.

Among the obvious shortcomings of the equipment of this brand should be the absence of a regulator – which is not very convenient.
