Replastered in April......test results from the past 3 months..what are my concerns?

Feel free to be curious but know that we can't give advice based on their testing.

Agreed but if you see my results from the test before that was me, the TA amounts are really close. I am trying to get my TA up enough to keep my ph stable....so my goal was 80. Right now my ph will run to 8.0 every week if I dont put acid in the pool.

Higher TA will make the pH rise quicker. Going up to 8.0 and adding acid weekly isn't uncommon. Pucks are acidic, and without them, CO2 naturally offgasses out of the pool (especially with that spillover I see in your profile pic aerating the water) and causes pH to rise.

If anything you want to keep TA a bit lower to slow the pH rise. Most people here aim for about 50 - below that and you risk pH crashing.

Just retested so these new numbers are in my log......TA jumped quite a bit to 110 from the baking soda I added a few days ago but my PH also was between 7.5 -7.8 so i called it a 7.6

I added some acid to pull down the TA a bit and a bit of Liquid Chlorine to keep my FC around 5.

started trying to increase TA to help stabilize my PH as it is still swinging higher a year after replaster.

Don’t pollute your PoolMath log with pool store results.

Increasing TA will not help stabilize your pH. Lower TA is better to slow the rate of pH rise. Your TA was fine at 50-60.

Target FC level for CYA 40 is 5-7 with a minimum of 3. You are letting your FC drop too low. You should be targeting FC 7, not 5.
