if your going reef you''re trying to max the light into the tank and salt creep on the glass can cut back on the amount going in. Also reef you're running higher wattages than say a fish only and a open top helps keep the temp in check, then there's the oxygen exchange thing...

Can just leave open but if concerned about jumpers the eggcrate's a good idea.
