Description

Experienced people usually only look at power when choosing a fish tank pump. They were just talking about a one meter small fish tank. If there are not many fish, usually choose a one-meter fish tank if it is an old-fashioned AC pump. A 25-watt water pump will suffice. If it is a DC variable frequency water pump, the power is reduced by 50%. But now it seems that this selection method is not so accurate. Therefore, when we choose a water pump, not only the power, but also the flow and head of the pump are also high. We don’t need to elaborate on the pump head. Suppose your tank is one meter tall and the pump head is only half a meter, then he has no water at all. Regarding the flow rate of the pump, we must also choose according to the species of ornamental fish we raise. For example, if we are keeping quiet ornamental fish, such as goldfish and small tropical fish, the pump flow should be 5 to 7 times the flow of the water body. That’s it. In other words, weProfessional pump manufacturers must ensure that the water in the fish tank circulates about 5 times per hour. If you are raising more active ornamental fish, such as koi or large tropical fish, the pump flow should be 7 to 10 times the flow of the water body. We have to make sure that the water in the tank circulates about 10 times per hour. The number marked with the pump flow indicates L/h, which is how much water per hour. For example, if your tank has a capacity of 200 liters of water, a pump with 10 times the flow rate should be 2000 liters per hour. The tank water volume is calculated by using the tank’s length and width as well as its height. The unit is in centimeters. The value obtained is divided by one thousand. The result is the number of liters of water in the tank. The algorithm is relatively simple, and then select the appropriate filter according to the liters of the fish tank. Like the bottom filter tank, we also have to calculate the amount of water in the bottom filter tank.
