I wonder if your books explained how the greatest medical discovery came about? How someone irresponsibly left a contaminated petri dish out and upon returning witnessed something that he might not have had he just tossed it in the autoclave?
It was happenstance and then observation. It wasn't divine knowledge handed down by the almighty. It was an error. It wasn't even a "hey let's see what this will do" or based on any prior knowledge - well that is if you believe the official story. Me? I personally believe it was based on Westerners observing Asian remedies, as they have been using fouled, spoilt foods and their derivatives for centuries as cures, prior to the discovery of penicillin. You know? The stuff witch doctors and medicine men used and then were co-opted by the pharmaceutical industry for profit.
Know how warfarin was discovered? Rotting animal feed. Now it's the most prescribed drug on the planet. I wouldn't have any issues with it if it weren't first used to eliminated rodents

Wonder who was the first to want to try that?
Heck I wonder who was the first reef head that thought dumping Stoli into their prized reef was a good idea or dipping their corals in insecticide was a good idea? The point I'm trying to make is, most discoveries come from random happenstance, random experimentation and plain old dumb luck. I view this forum as a place to explore and discuss unique and sometimes way out ideas about reef keeping, else all we need is a book or two of dated information to guild us. If someone wants to dump garlic, clove or ginger in there tank, so be it. Maybe something will come of it. Maybe not. But pontificating and claiming to know better than others just isn't right in this forum. Just sanyin'. Heck, I wouldn't be surprised to one day see a bottle of the stuff in the LFS for $29.99 :spin3:
