premier™ is a conditioner specifically designed for the planted aquarium. It removes chlorine and chloramines. premier™ is non-acidic and will not impact pH. Use at start-up and whenever adding or replacing water.

premier™ is a concentrated solution of potassium thiosulfate which removes both chlorine and chloramines. Although a thiosulfate-based conditioner is not recommended for saltwater aquaria because of the ammonia produced when it reacts with chloramines, it is perfect for the planted aquarium. The ammonia produced from chloramine by premier™ is predominantly in the ammonium form, and is thus rapidly scavenged by plants*.
