R, it depends on how easy it is to get into. Tell us about how the canopy will be constructed without the side doors. You need to consider how easy it is to get into for cleaning, feeding the fish and placement of the lights. The reason my 230 does not have a canopy at the moment is with the canopy on it feeding the fish would be a PITA. I want Tom to modify my canopy with the side doors so I can feed the fish without dragging a stool over each time.
