I have been trying to get my pool balanced out but have made some missteps due to misreading of samples. I do not have a good text kit. I have a 3-way basic Chlorine, PH, TA test. Currently My ph has dropped to about 6.8. I have directed my returns to break the surface of the water in hopes it will bring it back up while I'm at work today. I've read that 7 hours of aeration will result in .2 raise in PH. However, I'm not completely aerating nearly as much as if I put a air pump creating bubbles in the water. Should I add borax to bring the PH back up?
