Pool Glossary


  • BASE:

    Those chemicals of alkaline nature which will counteract the pH of an acid eventually neutralizing at 7.0. Common bases used around the pool would include Soda Ash, Sodium Bicarbonate, Sodium Carbonate, and Sodium Sesquicarbonate.

    When you shock your pool, the goal is to reach a high enough level of free-chlorine, measured in ppm, to break apart molecular bonds; specifically the combined chlorine molecules.  When breakpoint is reached with sufficient additions of chlorine, everything in the pool is oxidized.

    A combined bromine - ammonia molecule.  Unlike chloramines, which are strong smelling and offer no sanitizing properties, bromamine compounds continue to sanitize.

    A base such as Sodium Bicarbonate (Baking Soda), added to your pool will increase alkalinity which increases the buffering capacity of the pool; your pool's resistance to pH change.
