Thanks for getting back to me so quickly.
I'm trying to lower the pH with the acid. It seems a bit high.
You're right of course. I'll check the CYA container.
Again, thanks for the help.

I'm a little confused by my lack of CYA since I use a feeder with trichlor (it should be adding CYA, no?) along with 6% bleach. I've been going through quite a bit of bleach lately.
