Use and Care Manual

Calcium Hardness (CH): The measurement of
dissolved calcium in the water. The recommended
range is from 200 – 1000 ppm.
Clarifier: A chemical that helps clear cloudy water
by coagulating small particles in the water into
larger groups of particles. This makes it easier for the
filter to remove the unwanted particles.
Cyanuric Acid: A chemical that has the ability to
stabilize chlorine against loss due to sunlight.
Chlorine: A chemical from the halogen family that
operates as a sanitizer in pool water by forming
hypochlorous acid to kill bacteria and germs.
Corrosion: Deterioration of fixtures.
Filter: A device in the water circulating line that
screens out solid contaminants by passing the water
through a filtering medium. Common media are
sand, diatomaceous earth or cartridges.
Free Available Chlorine (FAC): After the chlorine
demand has been met, FAC is the measurement
of the amount of active chlorine in the water that
is available to destroy, algae, bacteria or other
contaminants. FAC provides protection against
additional contaminants as they may be introduced
into the pool.
Overstabilization: The buildup of cyanuric acid in
your spa water resulting from the use of stabilizer,
stabilized sanitizers and stabilized shock products.
Overstabilization (typically over 100 ppm) will
dramatically decrease the effectiveness of chlorine in
killing germs/bacteria and preventing algae.
Oxidize: Elimination of undesirable solids, colors
and odors.
