Thanks, I apreciate your candor and your willingness to show your issue as well as your confidence that you can fix it using the methods promoted here. This is my first year with our pool and I haven't had any problems yet, thanks to this forum, the Pool solutions site and all you moderators, but when I do, this post will help me to relax and deal with it. It seems like most posts are mostly panic, because we don't know what to do, so it's nice to read this.
