Ok. Well, hopefully your kit will arrive soon so you can test CYA. That is an important number to know because needed chlorine levels are dependent on that reading. (Any idea when it is supposed to arrive?)

Each jug of 8.25% bleach will add 3.4ppm of chlorine. For now while you are cleaning up your pool and until we know your CYA reading, I'd probably aim for keeping the chlorine between 12-15. Also, run your pump 24/7 while you are working to clear it and turn your SWCG off.

Your pH is ok for now.

I'm not familiar with that particular test kit. Do you add yellow drops to get the chlorine reading?

By the way, I'm assuming testing error on the CC test. I would be very surprised if you had a CC reading of 5.
