So much junk will get stuck in the tubes.
Just place the canister lower than the tank, so extend the tubes, having it like it is will make restarting it a pain. Air will get in and get stuck easier as well.
Canister tube tops should be a few inches below the water line. Basically how they show it, but I have no idea what tank size that is.
But if it was me, I would get a regular canister, not a fancy mini..
