Product Description For BioSmart 18000/30000/36000 The heart of a filter is its filter sponges: red filter sponges have fine filtration properties, because they develop their full function at a medium flow rate of water. This means that small particles of dirt are simply stuck in the sponge during the flow and thus removed from the pond water. But filter sponges not only do classic filtration, but offer a lot of habitat for the smallest bacteria. This small biological oasis ensures the implementation of toxins in the pond: toxic substances are converted into harmless, but algae stimulating substances (nitrification), which in turn are converted into naturally occurring gases (denitrification). Together with the blue and green filter sponges, they prove a clean filter performance. Box Contains BioSmart 18000-36000 Replacement Sponge Red
