Complete and concentrated conditioner for freshwater and saltwater. Removes chlorine and chloramine. Detoxifies ammonia, nitrite, and nitrate. Five times more concentrated than competing products.

Almost all manufacturers of pet aquarium products offer a chlorine removal product. However, none of these products can compare to the quality, concentration, or effectiveness of Seachem's flagship product: Prime®. Prime® is a complete and concentrated conditioner for freshwater and saltwater. Prime® removes chlorine and chloramine and detoxifies ammonia, nitrite, and nitrate. It is non-acidic and does not affect pH levels. An additional bonus for reef enthusiasts: Prime® does not overactivate protein skimmers.
