Wow..I've never even heard of that. It looks awesome!
Anyway, I can't see why that wouldn't be enough. I have a 40 gal
with only 40 lbs of live rock and an AquaClear 50 filter and my tank stays pretty clean - low nitrates, wastes, etc.
Have you considered a protein skimmer? Between the live rock and a skimmer - I'm not sure the type of filter matters all that much. The live rock is definitely the most important
