I completely agree and being the curious person I seem to be, I tend to seek out that information.
One other thing that is often misunderstood, is that although the water from the pond has all the bacteria we need, the bacteria won't colonize in the water. It needs solid surfaces to grow on. That's the reason there is media in filters. Without colonization, there won't be enough bacteria to do the conversions.
So even if you move water from your pond to establish a new tank or pond, the new set up will still have to go through the nitrogen cycle to grow enough bacteria to be effective. Simply moving water won't cycle the tank. Moving established media would be much more helpful since that is where most of the bacteria would be.
