I wonder how much flow you would lose with sucking that much air?
I would shorten your pipe and just leave it run over some rocks or something before it runs into the pond
The flow is already "there" at this point, it's already been on a 1200' downhill slope and I have found being at the bottom of the pond gains an additional 15' of drop. I may actually try and make a simulated airstone out of a tee that way I don't have an airline inside the 2" pipe.
Not sure but I think the more bubbles the better but Im just not sure, for a waterfall I lose the 15' of drop and I have tried the siphon at the top of the dam and it slows considerably
Sort of like this
