I searched around but couldn't find a good post on this but I'm sure I'm missing it.

I have a 13K gallon saltwater fiberglass pool. This is my 3rd year with the pool. The pool man is coming to winterize it soon. They always bring 8 gallons of chemicals (who knows what) and I always tell them to NOT use them. These are my levels below. Should I adjust anything before they come? This is about where I was last year and the year before and I have not had any trouble in the spring. But I was curious about best practice and where I should leave the Free Chlorine?

TA ~100
CH ~225
PH ~7.4
CYA ~60
FC ~5

Thanks
Tom

Then don't change a thing. A classic case of, "if it ain't broke,......"

I should add that those numbers are just fine and tweaking them to obtain "perfection" may result in an, "Oops!"
