Hi, all
recently i have flickering problem ATO switch when ph drop to 1.10
i know my ph gone so bad long time. so i just ignore that ph reading.
of course i re calibrated the probe but it goes back to 3's
so it usually 3's and when it reaches to 1.10 ph, ato going on/off like crazy.
atm i turn it off ato or plug out until ph come back 3's.
i think i have stray voltage in water so i am using some titanium to groud.
so what to do? what's main reason for dropping PH and why ato flickering when ph fails?

I've never seen this before.
Can you try adding this to your setup():

Okay, I will try update
But I found major problem which is ATO leaking!
Got home and checked ATO , found some brown tips at the end of ATO which rust a bit. So i took out the ATO and check the ph, it is going up 6.28 now and no flickering! Yay!
So I add some sealant at new ATO and put it back. Hope this will work!

Thanks
