Umm... I'm not sure if you're looking for macro suggestions, or people in MI, but I can suggest a few!
Caulerpa prolifera: before I got off my seahorse binge (where I never got a seahorse because I realized I couldn't care for them as much as they needed), I had a full tank of Caulerpa prolifera. It never went sexual. It grew in a 29 gallon tank that had a light from a freshwater startup kit that had never been replaced (low light). It never grew on any live rock. When I took the tank down for movement, I saw copepods in the tank that I had never seen before, and that I attribute to the prolifera. It looks amazing, as the blades slightly resemble seagrass. I could extoll on this all day, but I'll just summarize it here: you should get it, as it's awesome.
Gracilaria macroalgae: I have a red bushy form in my tank that attaches to live rock. If a fragment lands on a hard surface, be prepared for it to grow, and spread, and grow some more. Not really recommended, but provides a nice contrast for the prolifera. It, and the prolifera, now grow in the same 29 gallon, but are now illuminated with 96 watts of T5 HO Oddysea lighting.
What type of lighting were you thinking of? Sandbed? Live rock?
