Cleanup crew

[Ryanst]

I am getting a bit of detritus building up on my live rock I was wondering what would help clean it up in between water changes? My tank is a 240 gallon bare bottom mixed reef. Right now my clean up crew is like 20-50 astrea snails 6-10 mexican turbos. I guess I should add that I have 5 mp40s in the tank so flow shouldn't be a problem. Any suggestions would be appreciated.
