- Biological filter material, breaks down bacteria, eliminates nitrates which promote algae growth in fresh or seawater.
- Simply place the filter material in the internal or external filter and only replace it after about 6 months, after it has been degraded by bacteria.
- The bioballs are colonized by bacteria that form a thick biofilm. Under this biofilm, the oxygen content drops to such an extent that the bacteria there extract oxygen from the nitrates and thus eliminate them.
- Stabilizing effect on water: bacterial degradation processes generate acids that lower the pH; bioballs contain minerals that fix acids to stabilize the water.
- Contents: 100 bio-balls to break down nitrates in 200 to 300 liters of aquarium water. 1 ball / 2 to 3 liters of water.
