pH stuck at 7.5

FC=3.5
CC=0
pH=7.5
TA=130
CH=225
CYA=0
Salt=3200
Temp=86

So numbers were worse a few days ago, with pH at 8.4. I concentrated on pH 1st and got it down to 7.5, but that is as far down as it will go. Pool Math says to get pH to 7.0-7.2 to lower my TA to the goal of 70. What should I do?

Today, I've started tackling the other levels starting with CYA. I just added 2lbs (it's all I had on hand) of CYA. I'll keep adding 2 lbs at a time to get to the target of 75.

What else should I be doing?

You don't need to do anything.

CSI looks fine using your target CYA. I wonder if the water is really 86, though.....

Don’t go chasing a perfect TA....let your pH dictate things. Lower your pH with acid and allow it to go back up naturally. When it hits 7.8’ish.....lower it again. As you add acid your TA will come down too.

The main goal to lower your TA is to help control your pH increase. If your pH is stable.....rock your current TA and enjoy a beverage. Take a look at the ABCs of Pool Water Chemistry for some more details on these levels. ?

Most people would kill to have a pH stuck at 7.5, I would leave it alone.

Getting the temp from my AquaLink RS8 inside the house, but just confirmed with an instant read thermometer I use for cooking... 86.1.
