This kit converts any Penguin Power Head to sponge filter or reverse flow operation in minutes. Perfect for turtle/amphibian tanks or small aquariums. A converted Penguin Power Head has the capacity and the "muscle" to handle tough jobs with ease. The open-cell sponge efficiently traps and filters heavy waste as it provides vital biological filtration. And the reusable sponge slides off easily for cleaning or replacement. The converted power head can also be used to create unique waterfall effects (1.5" tubing not included)...and it's perfect for converting to super-efficient reverse flow undergravel filtration.
