Nearly all pet aquatics companies manufacture a product that removes chlorine. None of those, however, can compare in quality, concentration, or effectiveness to Seachem’s flagship product: Prime. Prime is the complete and concentrated conditioner for both fresh and saltwater. Prime removes chlorine, chloramine and detoxifies ammonia, nitrite, and nitrate. It is non-acidic and will not impact pH. A further bonus for the reef hobbyists, Prime will not over-activate skimmers.
