the fish tank circulating pump does not produce water? There are many reasons why the fish tank circulating pump does not produce water. It may be because the water inlet pipe is blocked, the screw of the impeller is loose, or the internal damage of the pump. In either case, it should be closed and taken out for inspection. If it can be repaired, it can be repaired. If it can't be repaired, it can be replaced. The function of the circulating pump is to make the water flow in the tank move, and the water flow is helpful to the filtration, so the water quality can be maintained.
should we pay attention to when choosing a fish tank circulating pump? 1. Power: When choosing a circulating pump, we should first pay attention to its power. Power has nothing to do with size. It is usually proportional to flow, but it is not absolute. Usually, in the optional pump, the smaller the power, the better, the smaller the power itself is a little lower power consumption, and it is not easy to produce too much noise.
2. Flow: The flow of the circulating pump is an important indicator, and it is also the primary consideration for buying a pump. Generally speaking, the flow rate is related to the volume of water in the fish tank, ensuring that the water in the whole tank can be circulated 7-10 times per hour, so that the water quality can be maintained, which is also helpful to the health of fish.
3. Noise: If the noise of the circulating pump is too loud, it will not only affect the rest at ordinary times, but also frighten the fish, so it's better to test it before buying it to see its noise. For a pump of the same size, the less noise, the better.
