For BioTec 5.1/10.1 and BioSmart 18000/30000/36000.?The heart of a filter are its filter sponges: Blue filter sponges have coarse filtration properties, because they develop their full function even at high water flow rates.?This means that larger dirt particles get caught in the sponge during the flow and are thus removed from the pond water.?But filter sponges not only do the classic filtration, they also offer plenty of living space for the smallest bacteria.?This small biological oasis ensures the conversion of toxins in the pond: Toxic substances are converted into harmless substances that stimulate algae (nitrification).?Together with the red and green filter sponges, they demonstrate clean filter performance.
