An air pump for aquariums is an advantage during the night since plants need light to produce oxygen. In thinly planted aquariums the air pump supplies the necessary water circulation. 

In aquariums with dense planting the air pump provides the aquarium with oxygen at night, since the number of plants means the oxygen concentration can drop to a dangerous level. When disease is present in the aquarium the air pump increases the oxygen level in the water, an essential condition for many medications 

Air pump is protected 

The ProSilent Safe backflow stop is TÜV tested and protects devices, such as diaphragm pumps, from backflow of aquarium water.
