Water Balance:
Water balance is important to the overall performance of your spa. Every spas water conditions are unique due to location,
water source, and frequency of use. Unbalanced water can damage the equipment, especially the heater element, make
water uncomfortable for the user, and decrease the effectiveness of the disinfectant. Damage to equipment caused by
improper water chemistry is not covered by warranty.
PH:
Simply, pH is a scale indicating whether spa water is basic, neutral, or acidic. Spa water should be slightly basic 7.8 is ideal
with an ozonator in operation. Low pH below 7.2 can corrode the spa equipment will irritate the skin of bathers and will
cause the sanitizer to be less effective. A low or high pH can be corrected by adding pH increaser or decreaser.
Alkalinity:
Total alkalinity is a measure of the alkaline in the water. This acts as a pH buffer or a pH stabiliser preventing large changes
in the pH. The total alkalinity should be between 80 to 150 PPM, ideally 120ppm.
Low total alkalinity causes:
• The pH to wander.
• Corrosive water.
• Ineffective sanitation by disinfectives.
To raise the total alkalinity add Alkalinity Increaser.
High total alkalinity causes:
• Cloudy water.
• Scale formation.
To lower the total alkalinity balance your pH more often.
Calcium hardness:
Calcium hardness is the hardness of the water due to dissolved
solids such as calcium.
Low calcium hardness causes:
• Corrosive water.
• Staining of spa.
To prevent this problem use a stain and scale inhibitor and,
DO NOT use water from a water softener.
NOTE: It is advisable to have your supply tested for hardness
and if needed adjust the hardness to neutral.
