I'm glad someone started this thread. I was just thinking the same thing the other day. I'm looking for other types aside from chaeto, doesn't have to be nice to look at, and doesn't go sexual and start growing in the display.What is your preferred macro algae to populate a refugium with? This is a clean start fuge. Dragon's Tongue Algae, Blue Hypnea Algae, Chaetomorpha Algae, Something else? The fuge will actually have a display section as well.
