Ok so I’ve left my pool all night and day without adding soda ash and I’m still under 7 ppm. Thats me trying to let things balance out. Acid pump has been off for days, not had any rain and nobody has swam in the pool.You are doing more work fighting against your automatic pH system then if you turned it off, let your pH and TA settle down, did manual pH testing and adding acid only when your pH hit 8 to reduce it to 7.6.
Stop adding baking soda or soda ash and let your TA and pH drift up.
My PH should have been gradually creeping up but it’s not. I’m really not sure what’s going on??
