Adjusting TA

[drmnjms]

I'm new to pool ownership. Got my second results and they are
FC 7
CC 0.5
pH 7.2
TA 130
CYA 40
Pool math says to lower ph. and aerate to lower TA. How long do I need aerate?

Welcome

Aerating will not lower your TA. Using muratic acid will lower TA and PH. I would NOT chase a TA number if your PH is stable. I'd be concerned about cc in the test though

How are you testing and chlorinating and what does your water look like?

Your pH is already low. Don't add any more acid.

I wouldn't even bother trying to aggressively aerate it to drive pH up. It'll rise soon enough. As it says in the article "You shouldn't lower TA just to reach a target number."

The TA recommendation is 50-90+. Which means if you're below 50, you pick a number between 50 and 90 as the target and it tells you how much baking soda to add. If you're in range -- and you are, because you're at 90+ -- just target whatever the current value is. Nothing needed. Easy.
