A complete and concentrated conditioner for both fresh and salt water. Removes chlorine, chloramine and ammonia. Prime™ converts ammonia into a safe, non-toxic form that is readily removed by the tank’s biofilter. May be used during tank cycling to alleviate ammonia/nitrite toxicity. Prime™ detoxifies nitrite and nitrate, allowing the biofilter to more efficiently remove them. Also detoxifies heavy metals found in tap water at typical concentration levels. Promotes the production and regeneration of the natural slime coat. Non-acidic and will not impact pH. Prime™ will not overactivate skimmers. Use at start-up and whenever adding or replacing water.
