thanks for the advice. i'll cross the scooter off of my list.
any recommendations for getting my sand clean (in addition to water quality, which i am attempting)?
i currently have 3 red legged hermits, 4 astreas and 6 nassarius snails. they all pretty much stay on the rocks, although the nassarius will also get on the glass. i'm a little disappointed in the nassarius, because i read that they were good sand cleaners, but they pretty much go everywhere but the sand! i'm hesitant to put the astreas down there, because i've read that they're more used to rocky surfaces and don't necessarily like sand.
