pH is the measure of the relative acid/base content of the water.
If the pH indicator is below 7.4, your water is too acidic and may
corrode your spa equipment and/or cause irritation to bathers.
If the pH indicator is above 7.6, the water is too basic and may result in
cloudiness and a scale formation in the spa. High pH also reduces the
effectiveness of chlorine as a sanitizer.
Proper pH control is essential.

“TA” is the amount of carbonate, bicarbonate and hydroxyl ions in the water.
Increasing TA increases water pH and acts as a buffer against pH changes. High
TA promotes high pH and makes the water resistant to adjustment. Low TA
makes the pH unstable and difficult to keep in ideal range.
Consult your dealer for methods to measure and control TA.
CALCIUM HARDNESS, STAIN AND SCALE
Calcium hardness can be very important. Water that is too hard (dissolved calcium
over 250 PPM) can promote scale formation, making deposits in the spa and
reducing your heaters efficiency. Water that is too low in calcium hardness may
also be harmful. Soft water (under 180 PPM) will more rapidly dissolve metals,
shortening the life of your spas heater or other metal components.
Staining and scaling are common problems. Hot water causes calcium to deposit
more rapidly. Some local water conditions may require the use of a stain and scale
remover. Please consult your dealer.
