Starting a reef tank

[Orion]

I am waiting to hear back about the Berlin classic. I am also going to look at another used skimmer tomorrow made by precision marine.It's there HOT model.If I buy that then I will still need tank,rock and lights among other things. I might even pick up some fish at some point! Would love to have some corals as well as they can be quite beautiful. Yes, I have been warned about the expense involved which is why I am looking used. Just having a good time right now learning about all the options available. Looks like a great hobby.
