Nope. Found the MSDS, here: http://www.kellysolutions.com/erenew...5_02_07_PM.pdf

But unfortunately:
So . . .
1. Your pH is OK.

2. Your CYA is not a problem -- just keep your chlorine on the HIGH side, DARK yellow on the tester. Use this page to interpret high result: http://www.poolforum.com/pf2/showthread.php/23555

Unfortunately . . . it's time to play 20 questions! Let's start:
1. Did the pool turn cloudy IMMEDIATELY after shocking? Within 24 hours?

2. Were there OTHER events that occurred prior to cloudiness, like a pool party?

3. Was ANYTHING else, except the shock, added to the pool prior to the cloudiness?

4. Have you maintained a CONSISTENT chlorine level > 2 ppm since shocking?

5. Have you inspected your filter cartridge? What sort of 'goo' is on it?

6. Are you running your pump continuously, or on a timer?
Meanwhile:
1. Keep the chlorine above 3 ppm at all times.
2. Run the pump 24/7.
3. Replace the cartridge, if possible.
4. Keep the pH between 7.2 and 7.8.
5. Do NOT use any more mystery shock; use the 10% bleach.
