The main thing I see is that for such high cya, your chlorine level isn't adequate. You have two choices. You can either do a partial drain and lower the cya level some or you can run higher than normal chlorine levels. (See the chart at the following link.) Either way will work. If you decide to do the latter, you'll need a test kit that can measure high chlorine levels and you should consider buying the one Ben sells at the sister site to this forum www.poolsolutions.com as it will do just that. Your ph and alk are fine. Also your calcium hardness is OK, but I definitely would stick with bleach - no cal hypo. (You didn't tell if it was a gunnite or vinyl pool.)
