    Need some help with High PH

    Got rid of my algae about 3 weeks ago. Thanks for the help with that.
    I have got everything in check (I think) except I am continuing to battle higher PH

    My test this morning.

    FC - 4.5
    PH - 7.8
    TA - 100
    CH - 340
    CYA - 40

    Temp 74

    I have been running my aerator at night while pump is running to help get my TA down. After the SLAM my TA was 130.
    I have been bouncing back and forth between 7.6 and 7.8 or 8.0.

    My acid demand test is usually 2 - 3 drops to get it down to 7.2 - 7.4. So I have added 22 - 33oz of MA and the next day the change is negligible.

    It takes awhile to get the PH and TA stable sometimes. I unfortunately have high TA and PH in my fill water so I battle this too. All you can really do is keep adding MA as needs when PH rises.

    All that aerating is causing your PH to rise. I have two waterfalls and SWCG (which also aerates the water) and my PH goes from 7.2 to 7.8 in 5-7 days.

    So if my TA is now more in line should I turn off the aetator and that should help. I also have a water fall that I run on a small trickle when the filter is running just to keep the basin from growing algae.
