My TF Testkit is showing my TA at about 60. It turns red at 60 and SLIGHTLY more red at 70. So it may be closer to 70. Is this too low? I have to frequently add acid to my pool as my PH rises quite regularly. I'd say I add about 40oz of acid every week. My plaster is a little over a year old. Should I look at increasing it? I thought having it low would keep my PH from rising (It NEVER drops). I'm wondering if I should raise it a bit with some baking soda or will that make my PH rise even worse?
Thanks.
Thanks.
