Thanks for the quick reply PoolDoc/Ben,

I've had trouble finding this thread when I get on a borrowed computer...never did and so this reply is via phone...

I have read everything I can get a hold of to learn pools. I actually started reading off the TroubleFreePool site and then found this site thinking there might be more discussion about the comercial side. Being limited in my current access to a computer and then to the actual threads or pages has slowed me up a bit. I gather you authored the Bens Best Guess chart. Wow what an honor. I soak up every bit of info. I'm hoping that I'll not be a helicopter because there's too much to learn. Thanks from Woodhaven.

I do have a question about the degredation of CYA over the winter but I suppose I should try and find the thread I saw your reply to somebody about it in and start there...
