sorry, your going to have to tear into it if you want to upgrade. Look around, many have altered thier hoods and upgraded nicely. You might even find a pre-fab hood deal. There are people that buy them, upgrade them and then you ship them your stock hood with some cash and they send you the upgraded one keeping your stock one to sell to the next guy/gal.
I personally like all brain corals so its worth it to me to upgrade, but if your really not commited to them, then I would have to say with the stock lighting, I would advise to stay with more softies such as Xenia, zoos, mushrooms, sun corals ect. Things that arent pigs for light.
