Hypothetical reef tank

[michika]

I'm about 90% sure that this is the way I'm going to go. I'm going to try and do an external overflow box so I can maximize the space in the tank. I don't want to go BB, so I'm sure that will be a problem I will have to deal with later.

I want a very random flow, so I guess I'll look into an Ocean Motion. I don't think I want to use a SCWD again, because, like you meantioned, of the headloss.

I guess that makes my next step figuring out what pumps to use, and how I may want to drill my new tank. Should I be looking at doing a few returns through the back of the glass?
