Biorb 45 marine with Sump Filter....Breaking all the rules..... The best in the World HD

My Biorb 45 has been set up for 7 months now and is looking and running perfect. I have a 25 litre sump filter underneath with a 900 litre p/h pump giving a total turnover of water of around 12 times an hour. I have corals anenomes and evrything else they say you cannot keep in one of these small tanks. I use standard biorb lighting on a 15 hour daylight and 9 hours of moonlight. In the tank I have 5 hermit crabs, 1 Fire shrimp, 1 box fish, 2 Clown Fish, 1 fireball Angel and 1 Lemon Peel Angel.
