What is the difference?

What is the difference between a FO tank and a FOWLR tank? (Other than live rock.) Does the FOWLR tank require special things?

FO has only fish. FOWLR has live rock and whatever's attached to it. Depending on what comes in on your rock, it doesn't require anything a FO tank requires, although a little more light than a stand 40w strip is good.
