If you have enough plants they'll suck the calcium right out. I keep coral
in some of my tanks to mitigate this and think nothing of using limestone.
Sandy probably wants it for killies though as that's pretty much what the
esteemed Mr. Binder keeps so it might not be a bad idea after all.

I've never needed that.

Bloodworms are pelagic. Tubifex living in the sand is not what you
want, when, not if they die they pollute the substrate something
