That's interesting, WB. Thanks for all the advice and help. You guys are great.

I checked my pH last night and it's still 7.5. Unprecedented for me to hold this pH this many days after adjusting.

The DE in the sand filter project has it running 2 1/2 to 3 pounds over normal. The water is gin clear, the best it's ever looked.

Oh, a following up on the thread title. I've had no noticeable issues with skin drying. It feels great to me. It will have to pass the big test over the weekend, my wife's opinion. She doesn't usually get in the pool during the week. I'll report back on her experience after the weekend.
