Setting up a 180 FOWLR with seaflor special grade reef sand.What size Koralia Magnums could I use for good water flow? I was thinking 2 Magnum 6's.Any advice is appreciated.:thanks:

For a FOWLR , two magnum 6's should me OK. However, most FOWLR end up to be reef tanks . So I would just get 2 magnum 8's now.
