CHEMICAL SAFETY TIPS

READ THE DIRECTIONS CAREFULLY
1) Always add chemicals to water, never add water to chemicals.
2) Do not mix chemicals.
3) Store chemicals in a cool dry place - out of reach of children.
4) In case of contact or if chemical is swallowed, follow emergency advice on product label.
5) Do not smoke near chemicals. Keep the container closed when not in use.

WATER BALANCE

Water balance is important to the overall performance of your spa. No 2 spa's water conditions are exactly
alike. The water source, location of the spa and frequency of use all effect the water balance. Unbalanced
water can damage the equipment, especially the heater element, make the water uncomfortable for the
user, and decrease the effectiveness of the disinfectant. Total alkalinity, pH, and calcium hardness must
be within the correct range to balance the water. 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 7.2 to 7.6; 7.8 with an ozonator in operation. A low pH below 7.2 leads to corrosion of spa
equipment and will irritate the skin of the bathers. The sanitizer will dissipate more rapidly. A low pH can
be corrected by adding a pH Increaser.
ALKALINITY
Total alkalinity is a measure of the alkaline in the water. They act as a pH buffer or a pH stabilizer
preventing large changes in the pH. The total alkalinity should be between 80 to 150 ppm; ideally 120
ppm. Tablet chlorine and bromine tend to gradually lower the alkalinity level.
Low total alkalinity causes:
 the pH to wander
 corrosive water
 disinfectants to be ineffective
To raise the total alkalinity, add ALKA RISE.
High total alkalinity causes:
 cloudy water
 scale formation
To lower the total alkalinity, add a pH Reducer.

CALCIUM HARDNESS

Calcium hardness is the hardness present due to dissolved calcium. The desired range is 150 ppm to 280
ppm.
Low calcium hardness causes:
 corrosive water
 staining of spa
To correct this problem, add a Scale Preventative. (Do not fill the spa with soft water!)
