supersaturation of oxygen
So I was reading one of the many books I have on aquariums this book is called (Advanced marine Aquarium techniques) by Jay F. Hemdal and one of the things it talks about is super saturation in the aquarium. My question is what are the odds of a normal home aquarium having to much O2?

It isn't supersaturation of oxygen that is the issue, but rather supersaturation of nitrogen. Both can become supersaturated easily if a pump receives air on the intake side (sump microbubbles, a pin hole leak on the intake, etc.). For larger pumps and systems, this air is then pressurized in the return, forcing air into solution. When that pressure is released (in the display), your fish essentially can get the bends. Just like for scuba divers, excess oxygen isn't an issue as the body utilizes it quickly.
If you have higher head pressure (big pumps, a downstairs filtration room...), making sure no air gets to the intake side of your return pump is very important.

At work it was numerous fish deaths in a particular tank that we couldn't figure out (no obvious disease, no odd water parameters, fish eating fine, etc.). We'd just kept losing apparently healthy fish every 2-3 days for no discernible reason. We only figured it out after bringing in a University of Florida extension service that came and tested our water with a gas saturometer (not a cheap instrument). They were able to measure our saturation (105%) and then confirm a reduction weeks later after we implemented several modifications to the system. Unexplained losses stopped after this, so it was likely the cause.

If you can see gas bubbles in the gill capillaries (and are sure that it wasn't introduced when cutting the gill clip), that is a pretty telling symptom.
