OWNER'S MANUAL
If the pH is too high it can
1 . Deposit scale on surfaces .
2 . Contribute to cloudy water .
3 . Cause eye irritation .
4 . Reduce sanitizer efficiency .
On the other hand, a high total alkalinity level keeps the water's pH rigidly fixed . If pH
adjustment is necessary, you will need unusually large amounts of treatment chemicals to
change the water’s pH.
Recommended Range: 80 to 120 Parts Per Million (PPM)
potential problems:
1 . pH difficult to maintain . If total alkalinity is too low, pH will drift .
2 . Corrosive tendencies . If total alkalinity is too high:
• pH difficult to adjust (it remains fixed.)
• Cloudy water.
• Potential for scaling.
• High pH and low sanitizer efficiency.
tEStIng WEEKLY
adjusting total alkalinity
Total Alkalinity can be raised with Alkalinity Increaser, or sodium bicarbonate at the
manufacturer’s recommendation for dosage.
calcium hardness
Calcium hardness is the amount of dissolved calcium in your spa water . Too little calcium in the
water will etch plaster surfaces, too much will leave deposits on surfaces and equipment .
Recommended Range: 125-150
potential problems:
Calcium Hardness Too Low:
• Some surfaces may be etched.
• May lead to equipment corrosion.
adjusting calcium hardness
Raise hardness by the addition of calcium chloride . Decrease calcium hardness by draining spa
and replacing with water containing lower levels of calcium hardness .
disinfectant
• Brominating Tablets, Granular Bromine and Granular Chlorine are popular disinfectants
and are particularly well suited to compliment your ozone purification system spa . They
are also very suitable products in water with elevated temperatures .
• Brominating Tablets and Granular Bromine are effective as a spa water sanitizer and
disinfectant. Follow manufacturer’s directions for proper dosage. It is recommended to
maintain an active bromine residual of 2 .0 to 4 .0 ppm .
• Granular Chlorine (Dichlor Dihydrate, Lithium Hypochlorite), is designed to dissolve
quickly and completely, provide a steady source of available chlorine to control the growth
of algae, kill bacteria and destroy organic contaminants . It is recommended to maintain a
chlorine residual of between 1 .0 and 3 .0 ppm . . Non-Chlorine type shock will oxidize or
destroy most of the organic contaminants that result from bather load . This quick acting
oxidizing shock treatment goes to work almost immediately improving water quality and
eliminating irritating wastes and odor . This product is intended to be a shock treatment
only, and is not a disinfectant .
Calcium Hardness Too High:
• May contribute to cloudy water.
• Scaling of surface, piping and equipment.
note: the use of biguanide, Salt
generators and other after market
sanitizer/ disinfectant systems may
damage components and void your
spa's warranty.
