Thanks water bear. I wish I would have read that first. I would have saved my self a few hours of reading but I did learn much more about Cl and its role in a pool.

Thanks for letting me know I didnt stomp any toes. The forum here is very helpfull and I have found myself spending way too much time here.

I guess the pool store is gonna have peps chanting and putting pins in little pool dolls before long.

Later
Steve
