Seachem Prime 250ml Water Conditioner

Prime® is a complete and highly concentrated conditioner for both fresh and salt water. Prime® removes chlorine, chloramine and 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, 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 remove both chlorine and chloramines from municipal water supplies.  Prime® also contains a binder that renders ammonia, nitrite, and nitrate non-toxic. Seachem Prime includes an ammonia binder to detoxify the ammonia produced in the reduction process.

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.
