Hikari Bacto-Surge Sponge Filter Kit – Large

The Hikari Bacto-Surge Sponge Filter Kit provides simple, dependable mechanical and biological filtration for aquariums up to 75 gallons. Its porous sponge traps suspended debris while providing a large surface area for beneficial bacteria to colonize, helping support stable water quality without creating harsh flow.

Because it is air-driven, the Bacto-Surge is especially useful in breeding tanks, fry tanks, shrimp aquariums, quarantine systems, and other setups where gentle filtration is preferred. The sponge is easy to remove and rinse, and the included uplift assembly keeps the system straightforward and reliable. Air pump and airline tubing are required and sold separately.
