A paramount factor in the proper maintenance of an aquarium is the dilution of accumulated waste by scheduled water changes. This requires the removal of chlorine and chloramine or both from the new water. With the advent of chloramine, thiosulfate has proven inadequate, causing the release of ammonia. At acid or neutral pH, this is not of serious consequence. It can however be devastating at alkaline pH, particularly if the tap water is heavily treated with chloramines. alpha is a concentrated conditioner for saltwater. It is 50% more active than Seachem Prime and 375% more active than the next closest competitor. alpha removes chlorine, chloramine, and ammonia. It converts ammonia into a safe, non-toxic form that is readily utilized by beneficial bacteria and reef inhabitants such as clams. alpha may be used during tank cycling to alleviate ammonia/nitrite toxicity. alpha detoxifies nitrite and nitrate, allowing the biofilter to more efficiently remove them. alpha also promotes the production and regeneration of the natural slime coat on fish. alpha is non-acidic and will not impact pH, nor will it over activate skimmers. Use at start-up and whenever adding or replacing water.
