Product Description For BioSmart 18000/30000/36000 The heart of a filter is its filter sponges: blue filter sponges have coarse filtering properties, because they unfold their full function even at a high flow rate of the water. This means that larger dirt particles get stuck directly in the sponge when flow, thus removing the pond water. But filter sponges not only do the classic filtering, but offer the smallest bacteria plenty of habitat. This small organic oasis ensures the implementation of poisons in the pond: toxic substances are converted into harmless but algae-stimulating substances (nitrification). Together with the red and green filter sponges, they prove a clean filter performance.
