pH Level
The pH level measures the relative acidity and
basicity of the water. The ideal pH level is 7.2 - 7.8.
When the pH level falls below 7.2 the water can
become corrosive. Low pH can cause damage to
metal in the equipment pack and heaters, exces-
sive sanitizer consumption, and skin irritation. A pH
level above 7.8 can be scale-forming and allows
metals or minerals in the water to form deposits and
stain spa surfaces.
Shocking
Once bacteria and other wastes are neutralized by
the sanitizer, they stay in the water unless oxidized
or shocked. Often called chloramines or
bromamines, they create dull, cloudy water and
can cause odor and eye or skin irritation. Shock
Treatment rids your spa of these wastes for clear,
sparkling water. Shocking is recommended once a
week or whenever the water appears dull or
cloudy or has a strong chlorine odor.
NOTE: A strong chlorine odor indicates that
the spa needs to be shocked – not that there
is too much chlorine in the water. A properly
balanced spa that is shocked regularly will
not have a chlorine odor.
