Use and Care Manual

GlossaryGlossary
Algae: Microscopic one-celled or multi-celled forms
of plant life that are black, green or yellow slime.
They thrive in sunshine and can interfere with proper
filtration and greatly increase chlorine demand. In
addition, phosphates in the water encourage their
growth.
Algaecide: A chemical formula used to kill algae.
Backwash: Sand filters require backwashing to keep
the filter working effectively. Most pre-manufactured
spas have cartridge filters, which require manual
cleaning, rinsing and replacement periodically.
Bacteria: Microscopic single-cell organisms of
various forms, some of which can cause infection or
disease.
Balanced Water: Water containing just the right
amounts of CH, TA, pH and dissolved solids so as to
prevent scale formation or corrosive tendencies (in
most spas you shouldn’t need to worry about dis-
solved solids because they are frequently drained).
Broadcast: A method of putting granular or pow-
dered chemicals into a spa by spreading them widely
over the surface of the water.
Bromide Reserve/Residual: Bank of sodium bro-
mide. Created when using HTH Spa
™
Brom-Start
to form an immediate residual of bromine to begin
sanitization instead of waiting for the brominating
tablets to dissolve.
Bromine: A chemical from the halogen family that
operates as a sanitizer in spa water by forming hy-
pobromous acid to kill bacteria and germs.
