I used flat. I let the back of the tank get covered in algae anyway, so for me it isn't important. I just didn't want to see the wall and wires and stuff.
As far as completely covering the tank, That may effect your ph more than you want it to. you may be able to attach a long air hose to the skimmer and put it out a window or in the other room maybe.
