OP - Not looking to overtake this thread, but I am in similar boat.
I am happy this is posted because I am about to order a clean up crew. I have 45 gallon tank from June and it appears that my CUC is understaffed. I do have a significant amount of hair algae that I am slowly working to get out. it grew a lot when I was in a fallow. All I have right now are 3 turbo, 3 blue legged crabs, and 2 nassarius. I had a few more, but 1-2 have disappeared.
By looking at these replies it looks like I have a skeleton crew. I submitted a request on tankcleaners.com and they came back with this:
50 Dwarf Ceriths - tiny cleaners, for the tight spots the others can't reach
9 Nassarius vibex
17 Florida Ceriths
14 Astraeas
2 Mexican Turbos
It just seems like so much.
