A wave-making pump of 8-12w is generally used for a 1.5-meter fish tank. Wave-making pump is a special equipment, which is not as common as filters and oxygen pumps. Its significance lies in periodically generating water flow, so as to ensure that all water layers flow, so as not to form stagnant water areas, which is helpful to maintain water quality. Moreover, the water flow formed by the wave-making pump can also blow away the residual bait and feces falling into the dead angle, which is convenient for filtration.

1. It is easy to muddy water: wave-making pump does not form stable water flow like filtration, but impacts once every once in a while. If the bottom of the cylinder itself is not clean, it is easy to cause the water body to become turbid. The turbid water body not only looks unsightly, but also has certain influence on the health of fish.

2, not very beautiful: the wave-making pump is generally placed in the fish tank, so it looks out of place. Generally, the water pump can only see the inlet and outlet pipes in the fish tank, and the air pump only has the air head. If it is hidden well, it means that it can't be seen, which will not affect the ornamental fish, but the wave-making pump is very abrupt, especially in the fish tank which tends to be natural.

3. Disturb fish: There are many kinds of fish, and the demand for water flow is different. Generally, seawater tanks need wave-making pumps, or some large fish can be raised, but it is not suitable for small fish to use wave-making pumps. Regular water flow will disturb fish and even produce stress reactions.
