So I pointed the returns up (they are in the shallow sun shelf) and they are splashing a lot of volume up and aerating well. Did that for about 2 hours and it raised the PH back up to 7.7... I have a feeling if I let that go for a while I could get it up to 8 so I would feel comfortable lowering the TA/PH and aerating to raise it again... I just want to reach that stable PH/TA mix, which I dont think im at today... We swam today and eye comfort was totally fine... FC was about 10 which is higher than we want of course, but no discomfort at all.. eyes were just fine as well.
