The Dymax IQ Skimmer is an air driven mini skimmer that not only fit into the IQ5 but to most nano marine aquarium. The wooden air stone diffuses the air into very small air bubbles. 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. (Works extremely well with Dymax eZ Filter) -Clip on device -Easy installation -Air driven system -Suitable for most mini tank
