Seachem Safe

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 transporting or quarantining fish, use Seachem StressGuard™. When adding new fish, use Stability®. Both are ideal for use with Safe™.
The standard dose of 100 mg/100 L of water will remove 1 mg/L (ppm) of chloramine, 1.4 mg/L (ppm) of chlorine and 0.33 mg/L (ppm) of ammonia.
Use 200 mg Safe® (scoop) per each 200 L as needed to reduce chlorine and chloramine or per 50 L for ammonia
