mess after vacation

Actually, your CC is way too high. Ideally, you want it to be 0 or at least no higher than 0.5ppm. When it is higher than that, you need to shock the pool to get rid of it. This chart shows needed shock level which is based on your CYA level. (http://pool9.net/cl-cya/) So, with a CYA of 35, your shock level is 15ppm. You want to keep the chlorine at shock level until you meet the 3 criteria which are listed in post #12 above.

Ok...still trying to understand:/ how much bleach will it take to bring the chlorine up that much? I will add a gallon now.

One 121 ounce bottle of 8.25% bleach will add 3.4ppm of chlorine to your 23,000 gallon pool.
