If you have the money, I would really consider a fuge. I can't really think of any negative aspects of having one, but there are so many on the postive side. The macro will help you stablize the ph, provide food for all kinds of critters. It can be a good place for a stressed out fish to hide out for a little while in abundance of food. The macro of course will inhibit the growth of the undesirable algeas in the tank. With a fuge, you don't have to deal with bio-balls. Its a good place for hiding your skimmer, and any media you might eventually use. I lucked out with my fuge price wise when I purchased my tank, but they could be pricey, considering that its made from inexpensive plastic. But, if you have some extra cash, imo its a good purchase.
