Thanks for the great replies guys. I did try raising the FC level to about 20 for 36 hours. I also thought that if this stuff lives in strong concentrations of FC, Shocking would have little effect. I did put about 3.5 jugs of the Cloromax tainted bleach in the pool. Sun, time, shocking and filtering have not reduced the smell one bit. I haven't tried the MPS shock recommended as by JoyfulNoise, but I don't have much faith in that at this point. I'm nervous about draining a fiberglass pool that has been full for 15 years in a very hot and cold climate. I gave the local fiberglass pool installer a call asking for help checking for water under the pool and possible bracing of the side walls. BTW its a Viking Rockport pool.
If anyone is curious about what Clorox added to their bleach with Cloromax, I found this link below. It's a long complicated article of chemicals etc.

There are several threads over at an aquatic artificial reef site were folks were also fooled by this additive. They apparently use bleach in their cleaning process. The also stated that the residual is deadly to fish...
