Other Water Chemistry
Considerations
Note:
When water evaporates, minerals
from the water and the chemicals
are left behind. As the level of these
minerals increases, water treatment
becomes more and more difficult.
Therefore, at some point (between
4-12 weeks, depending on use), it is
easier and less costly to drain and
refill the spa instead of continuing
to treat the same water.
An Ozone generator will supplement disinfectants and provide the follow-
ing benefits:
- kills bacteria and viruses
- destroys matter which might discolor water
- does not affect the pH level of the water
- safe for bathers and equipment
- has no "chemical" smell
- automatic and requires little or no maintenance
- reduces the need for disinfectants
Refer to your ozone generator owner's manual for information on service
and maintenance.
Total Alkalinity-
Total Alkalinity is important because it helps to keep the pH in the
proper range. Test with an appropriate test kit, and adjust as needed
following the instructions supplied with the test kit. If you are using
trichloro-s-triazinetrione as a disinfectant, adjust to 60-100 ppm. If
you are using bromine as a disinfectant, adjust to 100-150 ppm. Higher
levels may cause cloudy water and scale formations, while lower levels
may lead to corrosion and uncontrollable pH variations.
Calcium Hardness-
Proper calcium hardness levels will help you to maintain other water
quality values such as pH and total alkalinity, and help to avoid cloudy
water and/or scaling on the tub surfaces, equipment, and piping.
Maintain the calcium hardness of your spa at 200 ppm when using
trichloro-s-triazinetrione as a disinfectant. For bromine, maintain the
calcium hardness between 150-300 ppm. Test with an appropriate test kit
and adjust as needed, following the instructions supplied with the test kit.
Total Dissolved Solids-
Tap water contains 50-300 ppm total dissolved solids [TDS]. When the
level goes above 1500 ppm in a spa, the efficiency of sanitizers is reduced
and corrosion is accelerated. To reduce TDS levels, replace some or all of
the spa water.
