    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.

    The ability of the pool to resist changes in pH, which prevents water balance.  The buffering capacity is given by the alkalinity, a close cousin to pH.  If your pH bounces, or resumes previous levels soon after adjustment your buffering capacity is too low.  Check your total alkalinity.

    Known as scale, crystalline deposits of calcium may form on your pool surfaces, equipment, or even line your pipes like cholesterol in your arteries.  Properly balanced water can prevent this.

    The flaked calcium salt used to raise levels of Calcium Hardness in your pool water.  Also good for snow melting.

    A titration test is used to determine levels of the mineral calcium dissolved in the pool water.
