Further Attributes of Hydro Sponge Filters:
Capable of moving more water than other sponge filters.
One inch diameter lift tube allows for high volume water flow and allows use of power head without adapters
Raised off bottom, no dead space.
Heavier base.
Can be used in the vertical or horizontal position.
Easy to clean. Just rinse and squeeze in used aquarium water (never tap water).
Made from Patented reticulated filter foam for higher flow rates and larger bacterial colonies, no other sponge filter compares!
Extra sponges can be purchased and kept in the aquarium for quick bio-cycling of new aquariums, hospital tanks, or replacement of the old sponge when worn out
The HydroSponge Filter provides both mechanical and biological filtration. Aerobic bacteria colonize the sponge providing a bacterial substrate to facilitate the nitrogen cycle.
In addition, the Hydro-Sponge traps waste particles mechanically cleaning the water without trapping the baby fish.
Excels as a small tank or bowl filter, especially for bettas which have fins that can get easily trapped in HOB or other filter intakes.
Excels as a breeding filter, as baby (fry) are not trapped by sponge filters
Excels as a Discus filter, angelfish filter, hospital filter, or back up filter. Even as the
Primary filter
