    Providing biologically-active filtration to a new tank is no longer a problem with Cycle! This super-concentrated formula works in freshwater and saltwater aquariums to keep fish healthy. Its all-natural formula is safe for all plants, animals or humans. Because of its biological filter-enhancing nature, it is ideal for use when new fish are added to your system, after medications are administered, or of course for new aquarium setup. Each dose works to reduce dangerous ammonia and nitrate levels in your aquarium as well.

    I used this for several years. swapped to a cheaper one, still good brand but cheaper, thinking "bacteria is bacteria". I'm back with cycle and won't leave again.

    I've used this for several monthes along with three other good bacteria aditives (See Nitro-Max Review). I like the results. It seems to stabilize the good bacteria strains so the bio-cycle doesn't cycle in such a large swing? Once stabilized I can fine tune the water balance for the best results.
