It can be done no problem with a 10g or 5g aquarium, some acrylic, some silicon sealant, plumbing and a pump. Get some
live rock and
macro algae for your
refugium side and you should be set. Oh! I almost forgot about and drilling the display tank!
If you don't mind me asking, is it still a nano if you plumb a
sump to it?
