Hey guys. I'm new to the hobby but have been doing a lot of homework and spoke with some guys at my LFS. I just ordered a 250 and I know it comes with the essentials to get the tank up and running. I'm planning on getting live rock and eventually adding some corals once the tank is here and built. Before all of that though, I just wanted to ask fellow 250 owners what other things should I buy before setting everything up?
