Thanks Al for the comments. I have always said there is nothing that running the the filter 24/7 and using the proper chemicals won't cure.

Am I wrong in the case of high CYA? What is it and does it happen often in vinyl pools? Would draining to 6" and refilling be OK?

Matt, any updates on the neighbor's pool?

Strange, I am loaded with questions tonight. Actually, it's way past my bedtime and I am questioning everthing.
