Saltwater prep - do I need RO/DI?

Awesome! Ok thank you guys, I really appreciate the advice! I'll probably just do a FOWLR setup for now to get started in sw, and worry about a nano later when I have some $$ freed up.


Thanks so much!

I wouldn't recommend all three of those fish in a 12 which if I remember correctly has a smaller footprint then a standard 10.. the clown would be a little crowded but could work after that though id only add 1 other fish like a goby...after that give it some time and check your parameters before thinking about the third fish because your nitrate levels need to stay considerably lower then in FW
