I guess we cannot judge which lighting scheme is better than any, that is to say if there are any better ones out there. That said I have 5 gal fuge with 65w pc. Needless to say I have great algae growth. But I am wondering if there are limiting factors on algae growth? Would it be watts of light, bioload, room in the refugium itself, or water current? I would like to know from all of you what size refugium, how many watts of light above the refugium, gph water flow, and finally how big of a bio-load do you have (don't get too detailed just sum the 3 groups of animals up). I think these combined will help anyone interested to figure out a good formula for designing a refugium.
