Natural substrate for freshwater aquariums
– Ideal for plant care: substrate for freshwater aquariums.
– Prevents algae: effective settlement of soil bacteria and optimum root growth due to natural pore structure.
– No unwanted pollutants released into the water. Round-shaped granule grains are gentle on sensitive barbels.
– High storage capacity: the natural substrate absorbs the surplus nutrients and releases them when required.
– Support of the filter due to huge colonisation area for pollutant-degrading bacteria
