Who's your favourite (or not) sand sifter ?

Yeah, same with mine. They only move the sand on the bottom, and make little holes and mounds. Any coral on the sand could get covered, but not on the live rock. Having said that I have some mushrooms growing down on the sand, and they seem to always get uncovered on their own. One thing that is important, though, is that your live rock is sitting on the glass bottom, not on the sand, which would be undermined and cause shifting.

I should mention too, that my sand is the larger coral rubble type, not the fine sugar sand.
