Your CC is 0. That's good. How does the pool look? Your pH reading will be artificially high at anything above 10FC. So, don't worry about that for now. As Watermon said, retest at dusk. If your reading is less than 15FC, top off using the same math as before. That is... if 407ozs of the 8.25% added 10FC, then 40.7ozs will add about 1FC. Be sure the pump is on when adding bleach. Retest again tomorrow morning. You ideally want to have no more than 1 FC loss overnight to know your shock is successful.

Good luck
