Hi Henry ,

THe one thing I am absolutely sure of , no matter what methods are used, Its Easier to keep up with the pool , then it is to catch up to the pool (cheaper too)

I have a confession to make , but dont tell anyone I told you this , ok? I dont test everyday and I dont add bleach everyday. Would I go a week without testing or adding bleach ? NO way!!! because I know I would be playing catch up big time...But we've had a pool long enough that Im pretty confident of its "trends"..even still , I would rather spend Five minutes testing then a Saturday afternoon scrubbing and shocking

Just my .02 , the best method is the one that works for Your pool , not mine or anyone elses
