For BioTec 5, 10 and 30. The heart of a filter are its filter sponges: Blue filter sponges have coarse filtering properties because they unfold their full function even at a high flow speed of the water. This means that larger dirt particles get stuck directly in the sponge during the flow and are thus withdrawn from the pond water. But filter sponges not only do the classic filtration, they also provide the smallest bacteria with plenty of living space. This small biological oasis ensures that any poisons that have arisen in the pond are converted: poisonous substances are converted into harmless but algae-stimulating substances (nitrification). Together with the red filter sponges, they demonstrate a clean filter performance.
