Developed in collaboration with one of Australia's leading aquaculture companies, it combines fast growing heterotrophic bacteria with true nitrifying autotrophic bacteria.\u003c\/p\u003e\n\u003cp\u003eThe heterotrophic bacteria rapidly consume ammonia in new aquariums, while nitrifying bacteria including \u003cem\u003eNitrosomonas\u003c\/em\u003e, \u003cem\u003eNitrobacter\u003c\/em\u003e and \u003cem\u003eNitrospira\u003c\/em\u003e form a stable biological filter that converts harmful ammonia and nitrite into safer nitrate.\u003c\/p\u003e\n\u003cp\u003eProduced in sterile laboratory conditions in Australia, Nitro Cycle maximises the viability of beneficial bacteria to help prevent new tank syndrome and support the safe establishment of your aquarium.
