Trying to switch over to bleach and add borates.
Started with these results:
500 gallon hot tub. Says it'd be 0.9oz to lower the pH to 7.0 and get TA to 50 unless I interpreted that incorrectly. Added half of the 0.9oz, aerated for a cycled an retested. TA still shows 60 (tho in reality may be between 50 and 60) but the pH went up to 8.0. You'd think with any acid in there it would have least dropped a bit even if not all the way down. Added the other half. Tested again after a cycle with aerating. TA still 60'ish per Taylor kit and pH MAYBE went to 7.8 (tho by color it's really between 7.8 and 8.0)
Are we doing something wrong or do we just keep adding little bits of MA and repeating until we get a true 50 on the TA and then see what the pH is. Should I even test pH until I get a 50 reading on the TA?
