Nice size! I wish I had more width. I'm pretty happy with the height of my tank, but 36"!!!! Wow! I think closed loop or another option is the hidden Tunze Stream compartment. I've got design ideas in my mind on those. I hate the look of any visible equipment in my tank. There's also the hidden vortech compartment idea as well.
Go hidden, you won't regret it! The only piece of equipment visible is the 90' elbow that goes back and forth at one end of my tank - and I don't even like that! It blocks light as well.
