I also want to comment on my sandbed. I don't clean it with a sand vacumm, and if I stirred it you could see alot of brown sludge come out of it.
I had one sand sifting star and some snails. The snails (i can't remember the species, but they have light brown on the shell with white and are sand sifters also). My thinking was that the sand may be releasing nitrates/phosphates/etc, so I had bought 4 more sand sifting stars last week. I also just bought 3 more today. So now have 8 sand sifting stars, with the snails and a sand sifting shrimp. It can't hurt!!!
Plus with all those stars my sand bed is looking nice and fluffy/puffy with them going in and out of it.
