Prime is the complete and concentrated conditioner for both fresh and saltwater. Prime removes chlorine and chloramine as well as detoxifying ammonia, nitrite, and nitrate. It is non-acidic and will not impact pH. A further bonus for the reef hobbyist—Prime will not over-activate skimmers. No other dechlorinator can compare in quality, concentration, or effectiveness to Prime.
Features
Prime 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. It will also detoxify any heavy metals found in tap water at typical concentration levels. 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 Prime.
