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 following 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 disinfec-
tant. 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.
