If you can post a video, that would make everything a bit easier to visualize. I'd guess it all depends on what you want to stock the tank with. If you wanted to do a cold water, native tank with . . . say . . . rainbow shiners and Darters, they'd probably be in fish heaven with tons of flow and air!

This sounds like a LOT of flow, I don't think you need all that filtration and flow. The canister filter on its own should be fine. If you wanted all of that, I think that tetras or some things like hill stream loaches or plecos would love it.
