The only thing I regret is using the stand I got with the tank. Its short which is nice because I can sit in my office chair in front of it and its at the perfect level and I cawork in it without a step (helps being 6'4" tall too :P), but the floor underneath the stand sits about 4 inches off the floor and I don't have much headroom in the sump. From the top of the sump to the bottom of the opening is only 7" and I have 17" of height for the skimmer. Very difficult to find a skimmer that short
