fowlr / reef?

[nano10]

What exactaly is the setup difference between a FOWLR and a Reef. Is the filtration set up the same? I'm setting up a 55 and i'm trying to decide between a reef and Fish only.

In a reef salinity needs to be a tad bit higher.

Flow in a reef needs to be controlled so it does not harm corals.

You have to be more careful with certain ellements like copper and nitrates in a reef then in a FOWLR.

A FOWLR will not require equipment like calcium reactors.

Lighting is also different, reefs need light for corals, fish only need light to see.
