Clarify your water naturally and cultivate beneficial bacteria with these Polypropylene Bio-balls! They promote gas exchange and increase dissolved oxygen levels, then filter the water as the bio-balls combine with organic waste to dissolve it. Due to the unique geometric design of our bio-balls, the biological loads are maximized within much smaller filter areas.
