I have learned so much from this forum and think I'm doing a good job maintaining my first pool. Since I'm so enthusiastic about the TFPC method I've been telling all my pool-owning friends about it. Well they keep looking at me like I've got two heads. When I explain why I like this method of maintaining my pool and avoiding the pool store the typical response I get is along the lines of, "well my pool has always looked great and I just take my water into (insert pool store name here) and they set me up. They never try to oversell me anything. They have been great." Now maybe all my friends have just been lucky and haven't been pool stored but I really have no snappy come back since they all seem so pleased and think I'm nuts for buying a "fancy" test kit when I could just take my water in and have some one else test it. I guess you can lead a pool owner to water but you can't make them test lol.
