Hah..I do have algae in that tank...and lots of it.Finding a clean-up crew that would'nt get eaten was a challenge.I have a diadema urchin,some blk& wht zebra turbos as big as my fist,a couple CBS',a couple atlantic spotted cukes,and a few mexi red legged hermits{they hide in the day}.
I would not recommend a sandsifting fish or star...they eat all of the infauna from your sandbed,and you need the organisms they eat.
