Aquarium Solutions Sponge Filter Small 40g

The Aquarium Solutions Bacto-Surge® Biological Action Sponge Filter Small offers outstanding mechanical and biological filtration for your aquarium. This air-driven filter, which requires a separate air pump, features a highly porous sponge with an extensive surface area and numerous microscopic pores. These pores are ideal for supporting the growth of aerobic bacteria that contribute to a clean and healthy aquarium environment.

Perfect for both freshwater and marine applications, this filter excels at maximizing bacterial colonization due to its unique sponge design. The soft sponge material is easy to clean and made from durable polyether foam, ensuring a long service life. The filter includes an uplift tube and air diffuser that enhance water circulation and prevent clogging. Additionally, it can be used as a polishing filter for canister filters, hang-on filters, or as an uplift tube in undergravel filters. Its finer pore structure allows for superior bacterial colonization compared to similar-sized foam filters from other brands.
