I live in Iowa and have been using 1 gallon bleach bottles to keep up the required level. I have a 24ft round a/g pool. Is there any type of chlorine dispenser out there I can hook up to the system that is reliable? I keep up with my pool usually daily and have never had problems since subscribing to poolsolutions in 2001 and following Ben's advice. This is when I set up my pool for the first time and have never added any chemicals not recommended on this site. Roger
