With a CYA of 60, you should never let your Cl get below 5 ppm, or you will get an algae bloom, as you have already seen. To clear it up, you need to add bleach to get your pool to shock level, which is 20 ppm with a CYA that high, and hold it there by re-testing and adding enough bleach to get back up to 20 at least a couple of times a day. In addition, you need to brush daily and run your filter 24/7, since the bleach will kill the algae, but the filter is what removes it from the water. You don't mention how many gallons your pool holds, so I have no idea how high your Cl is with 10 gallons of bleach, but to clear your pool you need to sustain 20 ppm Cl until the pool goes back to blue/cloudy, then give your filter some time to get the dead algae out.
