My Goldline PC-8 controller with T-Cell 15 works fine, i.e., no error messages, but free chlorine generation appears to cease if I drop the chlorinator percentage from 50 to 45. While at 50, my FC level holds at about 5 solid pink but if I change the controller to 45% the FC disappears in a day. I would like to get to the SWCG sweet spot FC level of 2 or 3. Any ideas?
