For the normal maintenance of fish requires a number of devices. In addition to lamps and filters, pumps are needed for the aquarium. The pump is a filter and compressor together.
Some aquarists choose aquarium pumps. The wide distribution is explained by the advantages:
- silent work;
- portable design;
- by design.
A water pump is something that you cannot do without, it is necessary for important parameters:
- movement inside the reservoir;
- creeks and waterfalls;
- vessel filling;
- pumping water.
Based on the structure, there are three types of pumps:
- external (hang outside the glass);
- internal (in the aquarium);
- universal (combine installation inside and outside the tank).
How to choose
When choosing a pump, several factors are taken into account.
Purpose of use
Decide what functions the pump will perform. Attach a sponge for mechanical filtration. The device is used as the main filter or as an additional cleaner. Together with the tube located above the surface of the water, the unit will serve as an aerator.
To create the movement of water, a flow pump was invented: it mixes and saturates water with oxygen for stable parameters, simulates natural conditions for fish. It is not applied as an independent filter or aerator.
If the pump is purchased to fill the aquarium, the level of water rise is taken into account. For pumping, you need a hose that reaches to the place where the fluid will flow.
Productivity is calculated based on the volume of the vessel. At one o’clock the pumping of liquid is required 3–5 times more than in a domestic pond. In small aquariums, a pump up to 380 l / h is used. In containers of medium size – up to 600 l / h. For volumes from 500 liters, you will need a pump with a capacity of 5000–8000 l / h. The price of such equipment will be higher.
Excess pressure is detrimental to the inhabitants of the aquarium.
Type of reservoir
Apparatus with metal components are suitable for the freshwater reservoir, and ceramic for saltwater. There are also universal devices.
Despite the relative noiselessness of the pumps in operation, some models will be the source of noise. External pumps louder, consider, having the equipment in places of rest. The noise parameters can be found in the enclosed passport with instructions.
Often there are models of the following manufacturers:
Pumps with universal positioning. Attached to the suction cups, placed for salted and fresh water. Power is adjusted.
More often commercially available cheap pumps for small and medium-sized aquariums. Minimum productivity is 200 l / h.
Pumps for the aquarium are equipped with a suction cup and power adjustment. Models for tanks of different sizes.
Devices with a minimum capacity of 350 l / h. For medium and small containers.
- Aquarium system
Reliable devices with overheating protection, well proven. There is an adjustment of the power of the flow of water and power spectrum.
Universal pumps with different performance. Compact and silent.
Internal devices are attached to the surface with full immersion in water. This is a mandatory measure for the correct operation of the device. If two pumps are located, flows are set in different directions for continuous flow. External pumps are best located away from electrical outlets and electrical appliances to prevent short circuits in the event of a leak.
How to care
Caring for the device is reduced to periodic cleaning. The internal pump in the aquarium is turned off, after which it is pulled out. Filter parts are cleaned with aquarium water. If a sponge is used, it should be replaced in layers every 3–6 months. The raid forming on the submerged part is washed off with a brush. External pomp wash less often. The de-energized unit is disassembled and cleaned under running water. The filter is rinsed with liquid taken from a container.
Buying a pump should be taken seriously. Know the features of the aquarium, and what is required from the device.
