MAINTAINING THE PROPER pH BALANCE
The pH factor is a measure of the relative acidity or alkalinity in the
water. It is measured on a scale of 1 to 14. Pure water has a value of
7, which is neutral. Any value above 7 is alkaline, and any value below
7 is acidic. You should maintain a slightly alkaline pH level, between
7.2 and 7.8, in the hydrotherapy spa. Severe problems can occur
when the pH balance is not maintained within this range. If the pH level
exceeds 7.8, dissolved minerals can build up and clog the plumbing
in the spa jet unit. If the pH level falls below 7.2, the acid level in the
water will begin to corrode the metal parts in the spa jet unit. Also, the
sanitation agents in the water will not be effective if the pH level is not
properly maintained. Damage caused by improper pH levels is not cov-
ered under the warranty. To maintain the proper pH level, you should
test the pH of the water regularly. To test the water, purchase a pH test
kit at a pool and spa supplier. The pH reading should be between 7.2
and 7.8. If the level is too low, add a pH increaser (usually soda ash). If
the level is too high, add a pH reducer (usually sodium bisulfate). Test
the water again after ve minutes. See the instructions with your pH
test kit for additional information about testing and adjusting the pH.
