Thank you for the replies! I have a salt water system so the poolcalculator.com link is closer to what I was looking for...but I was actually hoping to find good old fashioned tables that I could print out, laminate and keep handy! (I am pretty old school about such things.) I can't figure out an appropriate search term to hunt for them. Perhaps I need to find a book about pool maintenance? (But so much would be wrong...)

Or maybe I need to spend an hour with poolcalculator and run a bunch of variables.

Any ideas?
Alison
