The sponge filter consists of an airlift tube (cubefilter) and a 10" x 6" x 6" Poret foam sponge (20 ppi) that is glued with silicone onto an unglazed porcelain tile. This filter is optimal for 50-75 gallon tanks. Over the years, we have tested several sponges in our hatchery and believe that this sponge (made by Swiss Tropicals) is one of the best on the market, as it does not clog quickly or fall apart like inferior sponges. The Poret foam used is specifically manufactured for aquarium and pond use; it possesses a much larger inner surface area than other filter materials (approximately 1,800 square inches per quart of volume), which permits more rapid and superior growth of bacterial cultures.
