A newly setup filter in which nitrifying bacteria has not yet colonized, does not have proper functioning to maintain the water quality. Green Bacter serves to nurture filtration bacteria and stimulates their activity. Effective not only when a filter is newly setup, but also when the bacterial activity declines.
Green Bacter promotes the propagation and growth of microorganisms in both the filter and substrate.
