Aquarium Solutions Bacto-Surge Foam Filters provide exceptional biological and mechanical filtration, using the highest quality foam sponge available to provide ample surface area for beneficial bacteria. A unique air dispersion design pulls water through at a higher rate for thorough filtration
Large surface area supports increased beneficial bacteria populations
Helps break down aquarium waste and remove suspended debris
Ideal mechanical and biological filter for small-to-medium tanks
Bacto-Surge filters feature higher foam density per square inch to provide maximum surface area for the beneficial bacteria that eliminate organic waste from your aquarium water. These filters also feature a unique air dispersion design that maximizes uplift to pull water through at a high rate, meaning more water runs through the filter in less time. Locking internal connectors prevent separation during use, and a heavy base keeps the sponge filter firmly secured.
