Water districts are using more chemical additives and delivering water of poorer quality than in the past. Therefore, fish keepers need ways to improve water quality for their aquariums and ponds, and to make fewer water changes to minimize the risks when adding new tap water. Kordon's AmQuel Plus fills these needs by controlling many problems associated with the nitrogen cycle and removing unwanted toxins introduced by municipal water districts.

AmQuel Plus does not interfere with the nitrogen biological cycle - it simply makes nontoxic what is normally dangerously toxic to fish and aquatic invertebrates at every step of the cycle. This also means that AmQuel Plus cleans up the nitrogen-based organics that accumulate and are a problem as the water ages in the aquarium or pond. AmQuel Plus lessens the need for water changes. 1oz of AmQuel Plus will treat 60 gallons of water at the recommended dose
