Seachem

Safe? is the complete and concentrated dry conditioner for both fresh and salt water. Safe? removes chlorine chloramine and ammonia. Safe? converts ammonia into a safe non-toxic form that is readily removed by the tank?s biofilter. Safe? may be used during tank cycling to alleviate ammonia/nitrite toxicity. Safe? detoxifies nitrite and nitrate allowing the biofilter to more efficiently remove them. Safe? is non-acidic and will not impact pH. Safe? will not overactivate skimmers. Use at start-up and whenever adding or replacing water.
