The Superfish Air Sponge Filter is a very simple but effective biological filter for small aquariums; such as quarantine tanks, shrimp tanks, nano tanks and fry raising tanks. Recommended for tanks up to 50L. Useful bacteria attach to the filter sponge providing biological filtration. Biological filtration is the action of bacteria in the tank breaking down dangerous ammonia, converting them to nitrites, and then the nitrites to the less toxic nitrates. Nitrates can be harmful to many invertebrates in high concentrations. The process of biological filtration, also known as the nitrogen cycle, involves the movement of harmful wastes through the filter. The biological filtration process will keep down the levels of ammonia and nitrite, but nitrate is removed by frequent water changes.

 

• Suitable for tanks up to 50L
• Perfect for quarantine and breeding tanks
• Sponge has large surface area for beneficial bacteria
• Space for additional media like Zeolite or Carbon
• 2 sponges means 1 can be replaced without loosing biological load
• Requires Air pump to function (pump not included)

 

PLEASE NOTE: This filter requires an air pump to function and does not work on its own. Air pump not included.
