OK so just started the 100g tank a couple of weeks ago and went by the Fritz Turbo Start 900 directions and did the "fish in" cycle. Everything is doing well and is starting to enter the ugly stages. So therefore, I'm looking into the BEST clean up crews there is, for this large tank. I own trochus, Mexican hermits and Scarlets for my smaller tanks. What would do best for the reef for this large tank?
