As far as outside appeal, I built a hood for it and then changed the lights to pc and it didnt fit anymore. So I am lazy. The timer I also should put on the inside but again the lazyness thing gets in the way. And to top it all off I am buying a brand new house, that at this point has a wall that is going to be cut to fit my new 220 gal reef. I am so excited I cant wait..........I think I am going to turn this one into a seahorse tank with a mated pair of perculas in there. Cheers............
