I change my mind weekly at this point. I still have time.Fiji Cube makes good stuff from everything I have heard. Definately a sleek and clean design. I have no personal experience with them though you could also do as Taylor suggested and drill from the bottom of the tank and put the pipes wherever you wanted. Drill some rocks and hide them inside that. A TON of work and your rockwork would have to touch the surface of the water but totally doable
I don't want the rock work to go to the surface. All the tanks I like do less rock so that the corals have room to grow.
