You need to get some chlorine in there or you are going to have a green pool. You can use some dichlor as it will add chlorine and cya at the same time. If you do so, however, it will take some time to build your cya back up and in the meantime, you are going to be losing chlorine fast and have to add it often. Another option is to just go ahead and add some cya directly and then just use bleach. That is what I do. (I also open to no cya each year.) If you decide to do this, add enough per label directions to get to an initial reading of about 30. Add it to the skimmer while the pump is running and then don't retest for it, add more or backwash for about a week to give the cya time to dissolve in your filter. Until you start to see a cya reading, you'll probably need to test your water morning and evening and each time add some bleach. After the cya gets dissolved, you'll be able to just test and dose it with bleach in the evenngs. A good cya reading is anywhere between 30-50, but we usually suggest dosing for the low end. You can always add more later if you decide you need more, but as you have already found out, the only way to lower it is to do a partial drain.

Your alk and ph are both a little high. Take a look at the thread at the following link for information on how to take care of that.
