Get your chlorine up to 20 and hold it there until it clears. You really need to test 2-3 times daily, and each time add whatever amount of bleach necessary to bring it back up to 20. Keep your filter running 24/7 during the process, and scoop out any debris you can. It'll clear up, just pour the bleach to it!

If you have a test kit that will test for combined chlorine, when that test result is zero, you're ready to let your Cl come back down to normal levels. If you don't, then keep the cl up until the water is clear.
