Filters--What do you use?

[SFBiol]

Just curious what types of filters people are using in their tanks. Since my 40 gal. tank used to be a FO tank, I still have my Whisper filter (HOB), but am looking for ideas to upgrade. What makes for a good reef filter?

LR and skimmer.

Well, I also use a Phosban Reactor. I have a UV but haven't run it for quite some time.

To add to ledford: a refugium with macroalgae.
