What is the ingredient of super shock --- dichlor or cal-hypo? Also, what was the ingredient of the non-chlorine shock? If your pool is cloudy, then you most likely have an algae bloom trying to start. You need to raise your chlorine level up to about 10ppm (assuming your cya reading really is 0) and try and hold it there. Test several times a day -- at least 2x and more often is better -- and each time add enough chlorine to bring the level back up to 10. In a 40K gallon pool, it will take a lot of bleach. You may want to see if your pool store sells 10 or 12.5% liquid bleach so it will be less empty jugs to deal with. If you do use regular 6% bleach, each gallon (4 quarts) will raise your chlorine by about 1.5ppm. Run your pump 24/7 while you are trying to clear your pool. Repost with the requested info.
