How often do you replenish your janitors?

Very rarely... I can do a better job of keeping that tank clean than any invertebrate can. ;)

FWIW though I think I have about 4 trochus snails and one red-legged hermit crab in my standard 20gallon tank and it looks pretty clean. There's really no point in adding anymore than this right now.
