The sponge filter consists of a cubelifter and a 5" x 5" x 5" Poret foam sponge (25ppi) that is silicone-bonded to an unglazed porcelain tile. This filter is optimal for 15-30 gallon tanks. Over the years, we have tested several sponges in our hatchery and believe this sponge (made by Swiss Tropicals) is one of the best on the market, as it does not clog quickly or degrade like inferior alternatives. The Poret foam is specifically manufactured for aquarium and pond use and possesses a much larger surface area than other filter materials (approximately 1,800 sq. inches per quart of volume), which permits more rapid and superior growth of bacterial cultures.
