How to Select Proper Fish Tank Water Pump

How to Select Proper Fish Tank Water Pump

The water pump promotes the circulation of water flow and increases the dissolved oxygen in the water. A fish tank water pump that is suitable for the fish tank size plays an important role in water quality management. At present, there are two types of fish tank water pumps that are suitable for aquariums: immersible pumps and amphibious pumps. As the name suggests, immersible pumps are also known as submersible pumps, which are used in the aquarium water body; amphibious pumps can be both used inside the aquarium and be connected to the outside of the aquarium through the water pipe for direct use.


when choosing a fish tank water pump, it is most important to select a suitable one. Factors that should be taken into account include the size of the tank, the form of filtration, the number of filtration materials, the raising density, and the size of the fish. The larger the capacity of the tank is, the higher the breeding density is, the larger the size of the fish is and the faster the metabolism of the fish is, so the higher the power requirement of the fish tank water pump should be. Specific considerations are as follows:



1. The volume of the water

Regardless of the size and proportion of your aquarium, you need to acquire the total volume of the water (including the filter) in the aquarium. Only when you get the volume of the water can you calculate the amount of filtered water flow required in the filtering.

2. Types of fish

The more active the fish are, the higher the metabolic rate is, and the greater the flow is required; in contrast, the flow required for quiet fish such as Poecilia and Spanish mackerel is of course smaller.

3. Raising density

The flow of the fish tank water pump must be insufficient if the aquarium is overloaded.

4. The difference between the technical reference of the pump and the actual flow

Sufficient lift and flow can be achieved only on the premise of sufficient power, so the power will be the first reference factor when considering the lift and flow. The lift of a water pump refers to the height to which the water can be pumped.

5. Cost performance


Buy the highest quality water pump at the most favorable price and achieve the best cost performance according to the requirements of your own aquarium and under the premise of appropriate power, flow, and lift. The quality of the water pump directly determines the noise, rust degree, wire safety, etc. The low-quality water pump will be great hidden trouble, so in the selection of a water pump, you must choose the merchants with good and high reputations.

6. Quality

The pump with poor quality will have a lot of problems, such as loud noise, rust of metal parts, wire cracking, and in operation, which will cause a lot of safety risks. Therefore, products with a good brand reputation should be considered first when choosing a fish tank water pump. Avoid choosing a poor quality fish tank water pump only for saving money.




7. Pipeline construction

No matter how powerful your pumps are, complex piping will increase the resistance and cause flow loss. Therefore, in the construction of pipelines, the inner wall of pipes should be as smooth as possible. Try to change directions as little as possible because the more the turns are, the more the losses are.

8. Filtration method

Choose the pump according to your filtration method. The greater the gap between the two levels is, the greater the flow loss is, and the larger the pump flow should be chosen to compensate for these flow losses.
