FX5 use it on my RSM 34G???

[Sydney]

Just wondering what thoughts are out there for using my FX5 on my RSM? I bought the FX5 last year, and barely used it on my 180g reef. Just really seems to be an overprice powerhead on a large reef. So it has sat unused for some time. I finally got motivated one day to pull it out and thought maybe it would be great on my RSM. The thought is, well I've got it, might as well use it. I could put the intake hose in the chamber before the skimmer and the outflow hose in the chamber after the skimmer.

1) Will it actually do much for my tank, in terms of filtering the water, or will it just use up electricity?

2) Does anyone have any great mods for the FX5?

3) Will it do harm or offer a "refugium" for pods in my tank?

Cheers!
