If it is a submersible pump, the water in the fish tank must be covered, because this kind of pump will emit a lot of heat in the working state. If there is no water cooling, the motor will be damaged because of the heat. Even if it is not covered, half of it will be submerged in the water, and water will be sprayed regularly to cool down. If it is an external water pump, it has good heat dissipation in its design, and it is not suitable for water.

2. What is the use

of the water pump? 1. Keep the water running: The water pump can make the still water flow. As the saying goes, running water is never stale. If there is stagnant water in the fish tank, the speed of water quality deterioration will be accelerated. Although the running water in the fish tank will slowly deteriorate, the speed of deterioration will be greatly reduced, so as to better maintain the water quality.

2. Convenient filtration: The water pump can make the water flow, so that the water can better pass through the filter material, thus enhancing the filtration effect. Filtration is another magic weapon to maintain water quality. It is mainly divided into two parts: physical filtration and biological filtration. Physical filtration can bring particles from water into the filter material, while biological filtration is responsible for decomposing and transforming dirt to avoid polluting water quality and affecting fish health.

3. Increase the dissolved oxygen: When the water pump is working, it can bring a small part of air into the fish tank, so as to increase its dissolved oxygen. However, this effect is not very obvious, especially when raising large fish, it often lacks oxygen, so more professional oxygenation equipment is needed.
