Thanks Cracker, I thought I had planned this tank pretty well. Already thinking about expanding to a 150 for a couple of reasons. I purchased a sump large enough to expand and have found it did not leave me much room under the tank. This has led to equipment and supplies being stored in the boss's space. I'm debating this upgrade though, since I'm not sure if it would be better to wait and let stuff grow until I have to move the corals or if it is better to move sooner and let the coral grow into the new space.
