Installed my RJ-60 last week. FC was high when I started up but I figured it would be fine and that it would creep down over the following days as I only had my SWG working at 70 as per instructions. I have had to lower the output each day as my FC was holding steady at around 10 and I need it around 3...So as of yesterday, I have it at 30% output and I was at 7 or 8...I can't remember. I am thinking I am going to get it around 5 and raise the output to 50%. All levels are perfect in my pool except FC. CYA is at 80. On the bright side...this SWG works like a champ!!!
