I cannot help you with your SWCG question, but someone should be along who can. I just wanted to tell you that you should get some bleach and put in the pool while you work out this problem. With that low of a FC reading and a CC reading of 1.0, you may have an impending algae bloom. Go ahead and shock the pool to the needed level based on your CYA reading. (Check the Best Guess Chlorine Chart in my signature below.) For reference, in your pool, each gallon (4 quarts) of 6% bleach will add about 2.5ppm of chlorine.
