I've got almost the same problem. Mine is the 18'x48", with the cs8110. I had the water tested a week ago, and was told I had no CYA, 0 FC, and needed salt (I put the 5 bags in when I first set up the pool 2 weeks ago). I put in the CYA and salt, ran pump for 3 days. Still was cloudy and now the water was burning our eyes. I had it tested today, and attached are the results. I am becoming very frustrated with this system. I cleaned the copper plates and metal bars with the 4:1 mix of Mu Acid twice, and ran it in boost mode the last two days, and I'm still at 0 FC. What gives?? It seems they don't want to be too helpful there if you aren't using them to maintain your pool. I do buy stuff there, but not enough to catch there interest.
Any help you can give would be great.
