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 transporting or quarantining fish, use Seachem StressGuard. When adding new fish, use Stability. Both are ideal for use with Safe.
