I don't recall off the top of my head if this is a gunite or vinyl pool, but I do sorta remember a pool that Ben was messing with. He took the FC up to some insane number like 45 or so. Maybe it was even 75? I don't remember but it was some crazy big number. Of course, that's only safe to do in a gunite pool, but if you're getting tired of beating on this thing that may be a direction you want to try. I'd use the 12.5% stuff to do that so you don't have to buy out your local grocery store.
