• take a water sample to your dealer to be tested regularly, or
• ask your dealer to recommend a pool test kit for water balance.
Element: pH
Range: 7.4-7.8
If it’s too low The surface of your pool can become
etched. Metal parts in the pump and
plumbing will corrode.
How to x Add pH increaser.
If it’s too high “Scale” forms on the surface of your pool.
The water can become cloudy. Equipment
can become damaged.
How to x Add pH decreaser.
Element: Calcium Hardness
Range: 200-400 ppm

calcium is taken out of the plaster, causing
the surface to deteriorate.

If it’s too high Rough, discolored deposits (“scale”) will
form on the pool surface and inside the
pool equipment.
How to x Drain or dilute the pool water. Consult
your dealer.
Element:
Total Alkalinity
Range: 80-150 ppm
If it’s too low It provides no buffer so that you constantly
get uctuating pH readings, which can
damage equipment and pool surfaces.
How to x Use an alkalinity increaser.
If it’s too high White deposits (“scale”) form on the tile
line. The plaster on the pool surface
becomes rough or discolored. The water
becomes cloudy or milky white.
