Would it be harmful in getting my pool to a pH of 7.3 or 7.4 range when I treat it with acid. When pH gets to 7.8 I drop it to pH 7.5
For kicks I sometimes check it & sometimes it’s a tad below 7.5, man it sure needs less chlorine the lower the pH is. It has gotten to the point where I don’t even bother checking pH until the chlorine demand goes up more than usual- then I know my pH is creeping up to where I need to be checking it.
FWIW, I had a calcium scaling issue (winter pH got too high for too long) that I tried to correct with various acid treatments that were unsuccessful, I haven’t re-plastered & won’t until I have to.
Current tests & been stable all summer- pool has behaved spledidly all summer
TA 50 & has been all summer & doing great
