If your CYA is STILL 60, then your shock level needs to be 20ppm. You'll need to hold it at 20 until it clears.
You didn't post your shock level or your pH. Chlorine works better when pH is on the low side. If it's high, like 7.8-8.0, you are hampering your chlorine. Try to keep pH in the 7.3-7.5 range.
