HOW IT WORKS. A wooden air stone diffuses the air into very small air bubbles. While the air bubbles rise through the water they remove protein waste from the water. The waste foam is produced above the water level and then rises through the foam tube into the collection cup. In this way, waste particles and toxic compounds are totally removed from the aquarium, which is the essential difference between this and other forms of biological filtration.
