On a related note, I just bought this sand, in what must be "Moonlight Sand" because it is very very fine, but it doesn't actually say the name on the package from what I can see. Can someone okay that sand for me? Is there anything wrong with anything in it? Thanks!

It's Caribsea as well. It is finer than their sunset gold, which is actually very fine itself. The only thing wrong with it is the level of fine grain can cause issues with getting into your filter and kind of destroying it. So it depends on how much you really love your filter and also what sort of filter you have.
From what I've gathered Caribsea does a pretty good job as substrate, though.
