25-35w pumps should be used in 1.2 m fish tank. Water pump is an indispensable equipment in fish tank, and its biggest function is to make stagnant water alive. Stagnant water is not flowing, which is especially suitable for bacteria and microorganisms to multiply, so the water quality is easy to deteriorate, which is also harmful to the health of fish. After becoming living water, because the water body flows, the water quality in the fish tank can be maintained, and it can also promote fish activities.
2. What is the function of water pump1. Strengthen filtration: There are many functions of water pump, but the first is to strengthen filtration. The water pump makes the water flow, so as to continuously flow through the filter material in the filter. Repeated filtration by the filter material can improve the water quality and maintain the environment, thus ensuring the health of fish and helping to maintain the activity of nitrifying bacteria.
2. Promoting activities: Fish have different needs for water flow, some like slow water flow, and some like rapids. No matter which one, proper water flow can promote activities for fish. When fish move, it can not only accelerate metabolism, but also prevent it from getting fat.
3, Adding dissolved oxygen: Usually adding dissolved oxygen has a special oxygen pump, but the pump has a similar effect. The principle is that in the process of water flow, the contact with air is increased, so that the gas is brought into the water. However, it is limited to increase dissolved oxygen in this way. Because the air area contacted by the fish tank is small and the water volume is relatively large, it is necessary to increase oxygen in other ways to raise some large fish.
