No you still have one pond, you didn't understand what I said then.Then you have two (2) ponds not one which was the original question.
If you have the little waterfall separating the main 2 parts of the indoor outdoor pond, then you have the glass lowered into the water 3" away from the waterfall and 4" down.
its not a separate system idk where you got that from lol
