Yea I saw that as well.. But over $500 for something that is more of a "convenience" than manually skimming my 24' pool? I like to think that I'm young and can find the time to do that my self. Besides, now that I have made the mistake of going With Pristine blue, and now I have to correct it. That's going to cost me some hard earned $$ right there. Since draining and starting all over again is really not an option, and I only put one dose of PB in I think I will have to follow the advice I've been searching here regarding switching back to chlorine. I kind of wish that I had never went to that pool store.
