This super biochemical sponge filter is a filter that keeps your aquarium clean.The filter provides mechanical and biological filtration for easy aquarium maintenance.As a mechanical filtration,it use the air-driven system to create suction,that allows the sponge to capture floating particles in the water and return filtered water to the tank.As a biological filtration,harmful wastes are biologically transformed into a relatively harmless substance by aerobic bacteria that accumulates in the sponge. This kind of sponge is also suitable for Discus breeding tanks,small tropical fish tanks and fry stock tanks.
1) The air tube can be stretched and contracted freely,when stretched,it can improve the water flowing.
2) Duck shap air output shap can make the water in the tank have a good circulation.
3) Supplying the water with much needed oxygen.
4) Reduces noise from air pump and consumes lowest wattage.
The illustrate to Use:
1.Before use,soak the Bio-foam in aquarium water for 5 mins.
2.During maintenance,always rinse the Bio-Foam with drained out aquarium water only.No tap water or hot water should be used at all.
3.When re-using the Bio-Foam,do squeeze the foam in the water to remove all trapped air bubbles.This will keep the filter stay submerged.
4.Suggest replacing the bio-foam every 6 month,to ensure the filtering effect as well as the growth of the nitrifying bacteria.
