I have a 72 bow that was predrilled with an overflow. As far as equipment I put the biggest sump I could fit (I built the stand so it really is built in) at approx 25 gal.. In the sump I have 2 150 watt heaters, a Kent Skimmer w/Rio 2500 pump, and A Rio 3100 return pump. Since this is a reef tank there are no Bio-ball or the like, filtration is carried out by 90#LR and 120#LS. For lighting I have a JBJ Formosa hood w/2X65W Acintic and 2X65W white.
Things that I would do differently or change in the future...lights. The shape of the tank is great looking, but does pose some lighting Problems. First the bow makes it difficult to move the light far enough forward. Second, the black hinge casts a shadow over the cennter of the tank when the light is moved forward. I think that I will eventually build a canopy with MH lights, but this is far into the future, I have to wait for the numbers on my credit card to re-appear.
