I'm sorry, I do not understand what you're asking. The water under the false bottom/drainage layer is just unwanted, excess water from misting/watering the plants etc. This is supposed to be siphon out (or removed somehow). The waterfall (if we're still talking about the commercial available, which we talked about earlier) do not have anything to do with the water outside itself.
I might not be answering your question, but I don't understand what you asking. IF you could elaborate, I might be able to help more

It all depends on what your background is made of.

And yes, Hydroton -> Plantation soil -> leaf litter sounds perfect
