Adjusting TA

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.
