Your best bet would be to test your chlorine levels in the evening after sundown, and test again in the morning before the sun hits the pool (don't run the SWCG during that time) . If you lose 1 ppm of chlorine or less in that time, then you don't have algae or anything else in your pool consuming your chlorine, and we can look to other causes for the cloudiness. If you lose more than 1 ppm of chlorine, then you have an algae bloom trying to happen, or some other water problem that is creating a chlorine demand. In that case, turn off the SWCG, shock the pool with bleach to 20 ppm (that level is based on your CYA of 60 ppm), and then hold it there by testing/adding more chlorine as needed to maintain that 20 ppm until the cloudy clears up, and until you can go all night without losing more than 1 ppm of chlorine.
