CYA and low pH

[ncpoolguy]

I added 4# of Clorox stabilizer to a skimmer with a sock in it. My pump runs 24/7. I checked it after 28 hours and it bumped my cya up accordingly, but my pH dropped from 7.86 to 7.52. I thought I had read cya doesn’t affect pH much. My plan is to aerate until it rises back up, but I’m curious if this sounds normal?

It did not effect pH much. No need to do anything special for your pH

Guy,

It has a very small effect on the overall pH of a pool.. Your pH of 7.52 is perfect, why would you want to change it???

There is just no reason to adjust your pH if it is between 7.2 and 7.9 .

Thanks,

Jim R.

Sounds absolutely normal. CYA is an acid (that's the "A" in CYA) and does have a moderate impact on pH. Water will aerate on its own, no need to enforce it.

Got it thanks! I guess I was just surprised it dropped that much.
