Let's talk about cleaning crews

I have... 4 snails in my 75g, and one hermit crab which I just bought in the past couple days cause it looked neat. All I've had for the past year has been those few snails(I think I lost one since then). I notice they make tracks in the very small film of algae that forms on the glass, but they dont seem to be very beneficial in my system, and I've found hermit crabs to be more of a nuicance than anything, producing alot of detrius and eating little algae. I had alot of hermits and snails in my tanks in the past, with the same result I have now.

Epoxy sandbed with no skimmer, just a fuge.... 1 clown, 1 pajama cardinal, 1 mandarin, 1 orange shoulder tang.
