Hang on back filter

[Mike7]

I've got a 75 gal. tank with live rock, live sand, and good lighting. Do you guys think 2 hang on back refugiums would be sufficient filtration?

One will be enough if you have live rock and sand. To me two would be a hassle to keep up with.

What lieve stock do you have. How about one refugium and one HOB skimmer like a Remora? Also, how much live rock do you have?

add a skimmer also and like slapshot said use one as a "fuge" for pods to grow in
