Water Quality Maintenance
Maintaining the quality of the water within specific limits will serve to enhance your enjoyment
and prolong the life of the spa’s equipment. It is a fairly simple task, but it requires regular atten-
tion because the water chemistry involved is a balance of several factors. There is not a simple
formula and there is no avoiding it. A careless attitude in regard to water maintenance will result
in poor conditions for soaking and even damage to your investment.
pH is a measure of relative acidity or alkalinity of water and is measured on a scale of 0 to 14. The
midpoint of 7.0 is said to be neutral, above which is alkaline and below which is acid. In spa
water, it is very important to maintain a slightly alkaline pH condition of 7.2 to 7.8 and total water
alkalinity should be 80•120 ppm. Problems become proportionately more severe as the pH moves
beyond the ideal range. That is the reason almost all spa water test kits contain a method to
measure for pH as well as the use of a sanitizer. Failure to maintain a proper pH level will cause
damage to your spa and void your warranty.
Warning:
For spas equipped with an ozone generator, DO NOT use any polymer based product, clarifier or
“perfect pH” in your spa. The ozone generated by the ozonator will break down the polymers in
these products causing cloudy water. To destroy bacteria and organic compounds in the spa
water, a sanitizer must be used regularly. A residual “Bromine” level of 3•5 ppm is considered
desirable and can be maintained by regulating the number of bromine tablets in a floating
brominator and the filtration cycles. If your spa is equipped with an ozonator, the residual bro-
mine level may be reduced to 2•3 ppm.
Important:
Do not use chlorine tablets (Trichlor). They may permanently damage the acrylic surface and this
damage is not covered by warranty. Consult your local pool and spa supply company for advice
on spa care chemicals and additives.
Many other additives are available for your spa. Some are necessary to compensate for out-of-
balance water conditions and others simply make the water feel or smell better. Always consult
with your local chemical supply company before using any new chemicals, as they may have a
reaction with chemicals that you are using.
Note:
Do not use soft water. This may damage the components of the spa and may void the warranty.
