Greetings from central Virginia! I just found your site a few weeks ago and already realize how much money you are going to save me. Stopped using the tri-chlor pucks at the beginning of the season but still trying to use up the big bucket of hypo-chlor the pool store sold me, and need to find a local source for bleach. Before finding TFP I just used the dip strips for testing, and would go to the pool store every few weeks for testing and would come out with several bottles/bags of stuff and a much lighter wallet. Haven't been back in weeks. Now I just need to figure out what to do with the new Hayward chlorinator I just bought last year.
