The Taylor PH test does not measure PH below 7. I want to keep my pool PH between 7 and 7.2. I'm testing if this PH level keeps my grey mottling issues in check, so far so good.
When the Taylor test result indicates my pool PH is 7 I'm concerned that my PH might be below 7. Because 7 is the lowest result in the range, can I be confident my pool PH is actually 7 or would PH in the high 6's (6.6 to 6.9) have the same color result as a PH of 7? Having a pool heater, I'm pushing the envelope keeping my PH low, just don't want it to go below 7, but have no way to confirm?
