Looking for some ideas for spiffing up the clean-up crew in our 55. We are down to 3 turbo snails and 5 reef crabs. Detritus and junk build up in/on the sand seems to happen fast, driving more water changes with the siphon trying to suck the crud out. Don't mind doing water changes regularly, but would like to avoid siphoning the sand all of the time.
I know many people like to increase flow to prevent the build up. We already have 2 powerheads running, on top of the Rio 2100 that powers our sump & return. Don't really want to add more powerheads, and drilling / external plumbing is out of the question for now.
Brittle or sand sifting type stars maybe? More crabs and/or snails? Conch's? Would be interested in the above is someone has some for sale (sorry, no frag's to trade with). Even if you don't have anything to sell, any insight, suggestions, and sharing your experience is encouraged & welcomed

..rounded up a bunch of them one night a few weeks back, and sacrificed them to the ceramic whirlpool. Thought there were too many in the tank at the time. There are still a number of them in there, we just have to search a bit more with the flashlight to find them. Perhaps we should have left them all alone.
