Bacto-Surge Sponge Filter Small

Advanced Air-Driven Sponge Filtration

Bacto-Surge® Biological Action Filters are air-driven sponge filters designed to provide superior mechanical and biological filtration for your aquarium. Please note, an air pump is not included. These filters feature a highly porous sponge that offers an extensive surface area and thousands of microscopic pores, fostering the growth of beneficial aerobic bacteria.

Ideal for Freshwater and Marine Applications

Bacto-Surge® Filters are perfect for both freshwater and marine aquariums. The highly porous sponge maximizes bacterial action, increasing the surface area for maximum bacteria colonization. The soft sponge material is easily cleaned and made of durable polyether foam for a longer lifespan.

Efficient Design and Easy Maintenance

The uplift tube and built-in air diffuser combination provide maximum lift and resist clogging, ensuring continuous filtration. Regular maintenance is simple, requiring only rinsing with aquarium water to preserve beneficial bacteria.
