Once I get ben's kit, I'll have a better read on the CYA. The good news is that the mustard is much, much less than it was, so the superchlorination with bleach obviously worked, albeit not completely.

By the way, seems like the autopilot is calling for a rather high CYA level at 60-80...anyone have experience with using a lesser level with the autopilot? Or maybe that level is just fine and my experience is with lesser levels....

Thanks for the help.
