I didn't read the entire thread, but soaking weed in water is normally called the "water cure", and is sometimes used when the weed is moldy, grown improperly, or has some sort of contaminant. Conflicting reports if it works or not.
It has not been proven to work 100%, and again is normally used by growers who mess things up in the grow process.
Let's just say I have some "Experience" with marijuana plants, I've experienced mold, tried the water cure and it was so-so, but I didn't really follow the directions to a T.
The best thing to do is grow your own, you can grow enough with a simple 400 watt CMH and tent, or if you can't, find a good dealer and stick with them. if you truly have nasty weed, try the water cure or save your lungs.
