I had previously gotten my pool "balanced" and with a pH level of 7.5. Everything looked and felt great.
However, lately I've been having some mild eye irritation and the water tastes a little different to me. It's hard to describe the taste, but it's unpleasant, almost like a faint taste of crushed aspirin.
I tested the following levels:
TA = 70, CH = 200, pH = 7.8, water temp = 67 degrees F <== EDITED (76 was a typo)
SI is between 0.0 and -0.1.
So the water is "balanced", but the pH is a little high. I'm thinking that's the cause for the eye irritation. But if I add acid to lower it, won't that also lower TA? The TA itself seems to be a little on the low side. Most things I've read say to target about 100.
So I'm not sure what to do. Add baking soda to increase TA or add acid to lower pH?
Thanks for any help. In general, is it possible to raise TA and lower pH at the same time?
