I would suggest taking it up to 20ppms until your water clears up, or you hold it overnight. It probably won't take long, because you have not shown any combined chlorine. You can tell it is all dead because your water will be clear, and there will be dead stuff on the bottom of the pool. Once the water is clear, or you don't use any chlorine overnight, you can let the chlorine fall back down to normal levels for your cya.
