It wasn't easy! My wife bought it and set it up with the stock lighting(would not support corals).Finally 2 years later,she's bored with it! So I bought a 150 MH and put a skimmer on and plan on a large amount os zoos! So far I have some orange rics,PPE's,PD's,Safecrackers,Tubbs blues(haven't opened yet,hope they make it),brown button polyps,yellow toadstool and some GSP.Still looking for colorful zoas and palys.
