Seachem Safe 250g
Safe™ is the complete and super-concentrated dry conditioner for both fresh and salt water. Safe™ removes chlorine, chloramine and detoxifies ammonia, nitrite, and nitrate. It is non-acidic and will not impact pH. A further bonus for the reef hobbyist—Safe™ will not over-activate skimmers.
Safe™ may be used during tank cycling to alleviate ammonia/nitrite toxicity. It contains a binder which renders ammonia, nitrite, and nitrate non-toxic, allowing the biofilter to more efficiently remove them. Use at start-up and whenever adding or replacing water. When adding new fish, use Seachem Stability. Both are ideal for use with Safe™.
Use 1.25 g (1/4 tsp.) for every 1,250 L (300 US gallons) as needed to reduce chlorine and chloramine or use 1.25 g (1/4 tsp.) for every 300 L (75 US gallons) for ammonia.
