About the Seachem Prime

Prime® is the complete and concentrated conditioner for both fresh and saltwater. Prime® removes chlorine, chloramine and detoxifies ammonia. Prime® converts ammonia into a safe, non-toxic form that is readily removed by the tank’s biofilter. Prime® may be used during tank cycling to alleviate ammonia/nitrite toxicity. Prime® detoxifies nitrite and nitrate, allowing the biofilter to more efficiently remove them. It will also detoxify any heavy metals found in the tap water at typical concentration levels. Prime® is non-acidic and will not impact pH. Prime® will not overactivate skimmers. 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®.

Nearly all 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 second most concentrated dechlorinator on the market after our own aquavitro alpha™. A single 100 mL bottle will treat 1000 US gallons of tap water. Prime® will remove both chlorine and chloramines from municipal water supplies.

Prime® also contains a binder which renders ammonia, nitrite, and nitrate non-toxic. It is very important to understand how those two functions work together. All dechlorinators operate through a chemical process known as reduction. In this process, toxic dissolved chlorine gas (Cl2) is converted into non-toxic chloride ions (Cl-). The reduction process also breaks the bonds between chlorine and nitrogen atoms in the chloramine molecule (NH2Cl), freeing the chlorine atoms and replacing them with hydrogen (H) to create ammonia (NH3).

Typically, dechlorinators stop there, leaving an aquarium full of toxic ammonia! Seachem takes the necessary next step by including an ammonia binder to detoxify the ammonia produced in the reduction process.

Be very careful when purchasing water conditioners. If your municipality includes chloramines in the water supplies, a standard sodium thiosulfate dechlorinator is not enough. Prime® promotes the natural production and restoration of the slime coat rather than relying on artificial or non-native slime compounds. A further bonus for the reef hobbyist—Prime® will not overactivate protein skimmers.
