Air pump accessories
At night an air pump with air stone is an advantage for the aquarium because plants without light don’t produce oxygen, but continue to consume it. In thinly planted aquariums the air pump with air stone supplies the necessary water circulation. When disease is present in the aquarium the air pump increases the oxygen level in the water, which is essential for many medications.
Connect the air stone to the hose of the air pump (not included), place the air stone inside the aquarium.
