Sponge Filter with Bio TumblerSponge Filter Included Fluidized media is the gold standard for aquarium filtration for two reasons: massive biological surface area and zero maintenance. While ceramic rings lava rocks clog with waste and lose most of their efficiency within weeks, moving bed technology is 100% self cleaning. The tumbling K1 media continuously sheds dead biofilm, maintaining maximum ammonia processing power for heavy bioload predator tankswith zero maintenance
