Can we see some pictures of the filtration?
BTW, a lot of people have said things about the nitrates your going to get in this tank. In my opinion, nitrates are harmless to fish, they do not affect fish directly. although they do indirectly (i.e. hair algae)
If it's invertebrates thats a whole other story, because obviously trates do affect inverts, but we're talking about a fish only tank here.
Although, I've done a large ammount of tests on various inverts and even they can do better then expected under high nitrates. One inparticular were a couple octopus that I tested on, where I had the species Bimaculoide in one tank with 20 ppm trates and another octopus of the same species with 200 ppm trates and the results were the same.
Sorry to bring up a controversial statement, but thats just my opinion, everyone has theres.
