Need some help with High PH

[ground_trooper]

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 74º

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.

Yes, that is correct.
