Hello all, I hope you can steer me in the right direction. I recently switched from a chlorinator to a SWG. The problem that I am having now is that I cant seem to get enough chlorine out of the system. I installed this system back in April and I had no problems with my water balance until about 2 weeks ago. I will post below my readings. The pool has always been clear and very balanced. I spend every day ensuring that the water is correct and so when I switched to a SWG system I thought it would be easier and it has turned into a nightmare. To keep any chlorine in the pool I have resorted to putting a chlorine tab daily to keep it clear but in doing so I believe I have driven up my CYA. The most FC that I have had over the past couple of weeks has been .05 with it mostly reading 0. I have had to shock the pool and then I got algae which I have never had before. You will see from my test results what I am talking about. If somebody could help on this matter it would be greatly appreciated. I am also interested in using the BBB method so if you could help in this also it would be great. This is an awesome web site.
