Aquarium Solutions Sponge Filter Large 75g

The Aquarium Solutions Bacto-Surge® Biological Action Sponge Filter is an advanced air-driven filter that provides exceptional mechanical and biological filtration for your aquarium. This filter, which requires a separate air pump, utilizes a highly porous sponge designed to maximize filtration efficiency. Its extensive surface area is filled with thousands of microscopic pores where beneficial aerobic bacteria can thrive, thanks to the oxygen-rich water.

Ideal for both freshwater and marine setups, the Bacto-Surge® filter excels in fostering bacterial growth that helps maintain a clean and healthy aquatic environment. The soft sponge material ensures easy cleaning, while its durable polyether foam construction extends the filter’s lifespan. The filter includes an uplift tube and air diffuser that enhance water lift and prevent clogging, ensuring consistent performance. Additionally, it can be used as a polishing filter for canister filters, hang-on filters, or uplift tubes in undergravel filters.
