pH goes up and down daily, being influenced by the number of bathers, rain, added water, calcium hypochlorite chlorine, bromine and if you raise the total alkalinity.
Trying to maintain it at 7.5 is not easy. The idea is to stay as close as possible to the 7.5
pH too high for a short period – chlorine doesn't work well, cloudy water.
Too high for months – chlorine doesn't work well, cloudy water and calcium or scale build-up.
WHEN YOU TEST
- If pH is too pink, use pH-
- If pH is too yellowk use pH+
PH TOO LOW ALL THE TIME?
Test and adjust the total alkalinity first, then the pH, otherwise you will be using a great deal of Ph+ for nothing.
PH TOO HIGH ALL THE TIME?
The pH will be too high constantly if you are using:
Calcium hypochlorite chlorine (sold at pharmacies or hardware stores) as its pH is 13, almost twice the desired level. Bromine Salt system
IF YOU'RE USING:
Calcium hypochlorite – change to trichloro, its Ph is neutral. Bromine – add pH- on a weekly basis
Salt system - use Primer and Acid Enhance (products specifically for salt pools).
