Good morning! Refilled pool about 80-90% due to high CYA. It was filled again by this Saturday morning. I Added about 3 pounds CYA this weekend to get it back up as nothing showed on CYA test (as expected) after the refill. I have been adding a quart or so of acid each day since according to pool math to start working down the PH. So far PH is just fluctuating between 8.3 and 8.4. I have been adding liquid chlorine as recommended each day as well. Anything else I can do to assist in lowering my PH? Am I being impatient lol? My test readings are attached here. Any help is appreciated. Thanks!

Your TA of 210 is rapidly raising your pH.
Are you testing your pH 30 minutes after adding acid?
Test pH and add acid in 30 minute cycles and you should get your pH into the 7s. But it will bounce back up in a day due to your high TA.
Here is the process to lower TA. But if you have high TA fill water it will be a continuous battle.

Lower Total Alkalinity
A lower Total Alkalinity level can help a pool owner stabalize their pH increase. We'll explain how to lower TA with a little help from muriatic acid.

Thank you I’ll try this tonight when I get home! I’d agree I have always required some acid each week to keep my PH in check.
Once I hit that target of 7.0 to 7.2 do I immediately aerate to try and swing the Ph back up? I have a waterfall so will attempt to accomplish it that way. Reading through various articles the 2nd challenge appears to be figuring out an effective aeration method. Anything simple I should attempt to do along with turning on our waterfall?Your TA of 210 is rapidly raising your pH.

You can aerate if you want to hurry the process along or let the pH rise naturally.

I have been at this all week lowering down to 7.2 twice daily. Roughly a half gallon of MA or slightly less each day. Encouraged to see TA is either 110 or 120 today (possible drop miscount). Hoping to find that moment of stabilization soon. Is there any concern putting this much or more in every day? I slowly pour in front of a jet I keep my pump in a higher speed for at least an hour after. I have started to swirl the pool brush after in the area and brush walls/bottom near the pour area. Do you have any other recommendations to minimize risk of plaster damage?You can aerate if you want to hurry the process along or let the pH rise naturally.

You have to get TA down between 50-70 for that.
Not if you keep on doing what you are.
