Turn off your SWG when you are SLAMing and when you perform an OCLT. Yes, use plain bleach no splashless, no scented, no outdoor. Wal-Mart generic is a great value.
Your test kit is limited and doesn't have the FAS-DPD chlorine test. You can order one from here:

You mentioned that your CYA is off the charts... did the black dot never disappear? If so, you don't have any CYA and your SWG needs CYA to be efficient. First, do the OCLT with a FC of 10 if your CYA is indeed zero. I always like to OCLT at SLAM levels, this way if you need to SLAM you have already started the process.
If you do NOT pass the OCLT, you should add enough stabilizer to get your CYA to 30. Use pool math to determine the amount of stabilizer and SLAM with FC of 12.
If you pass the OCLT, you should add enough stabilizer to get your CYA to 70. Add 1/2 the amount listed in Pool Math at a time. Retest CYA a days or two after it has been dissolved to confirm that you are halfway to 70... you don't want to overshoot CYA. Add the other half of the stabilizer to get to a target of 70.
