for a fish tank with 300 liters of water? Generally, a fish tank with 300 liters of water needs a 370 watt to 750 watt pump, with a flow rate of about 2000-3000 liters per hour. It is enough to ensure that the water can be circulated 7-10 times per hour. The flow of the pump should not be too large, otherwise the fish will always be in a state of high-speed swimming, which will affect its health. However, the flow should not be too small, otherwise the filtration effect is not good and the water quality is difficult to maintain.
the submersible pump 1. Cleaning and disinfection: The submersible pump bought can not be directly put into the fish tank. It needs to be cleaned first. It is better to disinfect it with potassium permanganate and other drugs to prevent it from bringing harmful bacteria into the tank. You can soak the whole pump in the disinfectant solution, usually for several hours, and then rinse it with clean water to avoid drug residues.
2. Installation test: The cleaned water pump can be directly put into the tank and submerged with water. After connecting the power and turning it on, check its use. Before this, it is better to check whether the rated voltage is consistent with the actual voltage, otherwise it may cause tripping.
3. Regular maintenance: The submersible pump must be maintained regularly. Take it out of the cylinder after cutting off the power supply, take it apart and clean it, especially wash the rotor and water blade. If there is too much dirt on it, it will affect its operation. In addition, if the pump body is broken, it needs to be stopped immediately.
