Bacto-Surge Small Foam Filter

Bacto-Surge^® Biological Action Filters are air-driven sponge filters (air pump not included) which offer superior mechanical and biological filtration of your aquarium water. The highly porous sponge contains extreme surface area and thousands of microscopic pores where aerobic bacteria, hydrated with oxygenated water, can grow and flourish.

 At Insidereef, we rely on Bato-surge foam filters for all of our freshwater tanks and quarantine systems because of their proven efficiency and reliability. These filters play a crucial role in maintaining exceptional water clarity and supporting the overall health of our fish by providing both mechanical and biological filtration. Their gentle water flow is ideal for sensitive species, especially in quarantine settings, where stable and clean conditions are essential. The consistent performance of Bato-surge foam filters allows us to uphold the high standards we set for aquatic care.Great For Use In Freshwater Or Marine Applications
