Hygger Bio Sponge Filter

Hygger Bio Sponge Filter — Large

The Hygger Bio Sponge Filter is a reliable, dual-function biological and mechanical filter powered by an air pump. The large sponge provides an enormous surface area for colonization by beneficial bacteria (Nitrosomonas and Nitrobacter), creating a powerful biological filter that processes ammonia and nitrite even in heavily stocked tanks. At the same time, the coarse sponge physically traps debris and particulates, keeping the water column clean. Sponge filters are beloved by breeders and quarantine specialists for being invertebrate-safe and impossible to suck up fry — and they're the most cost-effective filtration option available for tanks up to 60 gallons.
