Is the "Super Sock It" calcium hypochlorite? Is so, that's probably a primary or contributing cause.

Insufficient (and maybe inconsistent) chlorination is the other likely cause.

I recommend you ditch the "Super Sock It and bring your chlorine to shock levels using bleach. I'd go to at least 15 ppm but probably 20 ppm for your CYA level based on the best guess table.

I also recommend that you not use any more clarifier; it won't do anything for cloudy water and one of Ben's basic tenets is that you shouldn't add anything to your water that you don't need. Likewise the chlorine tablets; your CYA level is about where you want it.

Finally, your test results look as if they're from a pool store. Do you have a test kit? You need something (other than test strips) that will allow you to test pH and chlorine daily. Many here recommend the 5-(or is it 6)way kit from Wal-Mart as a stop-gap until you can get Ben's kit (or a Taylor K2006 or other with an FAS-DPD chlorine test).
