Hello,
This is my first attempt at a post so here goes...
It is cool to see photos of the Nano set up and running! Looking at the photos from deedee58, I see the drains are running right out of the back and there is a small loop on the drain. For better water drain and less noise, try adding 90's to the bulk heads (all of them.) and cutting the drain to a more direct fit without stressing the hose clamp.
I'd be a little concerned by the forces those three hoses to those bulkheads cause. They are trying to pull the back away from the sides. If you can you should support them somehow. Try to hold them up from anywhere other than the glass back.
