I recently purchased a house that has a pool. I knew absolutely nothing about caring for said pool. After consulting this site and many friends, I have a very basic understating of this pool now. But I continue to have issues maintaining the FC level. I have my SWG (I forgot the name of it) running essentially at it's highest level along with a pump that's basically running all day and I can barely get my FC level to 1. I'm adding CYA to it and currently have it at about 55-60. The salt level is 3200 and my other values all seem to be fine. So what am I doing wrong? Also, can you use chlorine based shock to shock the pool or do you have to use non-chlorine shock because it's a SWG pool? ANY words of encouragement and help are appreciated. Tyler
