Ever since the pool was installed last month, I've been working down the TA. Started somewhere around 280, it's currently at 130. Full results:
FC - 4
CC - 0
pH - 7.2 (was 7.8 - added 2C of dry acid today to get to TA 120. Yes, I know MA is preferred, but I'm super sensitive - skin and smells. Didn't want to chance it.)
TA - 130
Realized today that we probably need to top the water off a bit, so I tested our outside hose - it comes straight from the well with no treatment. Well water test:
TA - 20
pH - way more yellow than 6.8. I thought I had added the chlorine reagent for a second!
So.... I need to ask all of you smart people... I should probably wait until the pH comes back up to at least 7.8 before adding this well water, yes? And the low TA of the well water being added should only HELP continue to bring my pool TA down if it's diluting, right?
