Brand new to saltwater! Questions about sand! :S

[Feriation]

I'm just about to place my order for my brand new JBJ 28g nano cube! Seeing as I now qualify for free shipping with my order, I was going to order my sand too.

But I'm feeling very overwhelmed by the choices available to me. I realize buying live sand isn't really "live". I plan on seeding it with some sand from my LFS. I also know that I want Aragonite sand. But there's all these different kinds. I realize a lot of this must just have to do with cosmetic preferences, but is there anything specific I should be looking out for?

Oolite sand, special premium, Fiji pink, Hawaiian black...

I do really like the look of very fine sand, but would that pose a challenge for a novice like myself?

Hello,
only problem for fine sand is that if you have alot of flow in the tank, it would be hard to keep it in place.[at first, then after a while they colonize bacteria and get too heavy to lift off.]

but if that is what catches ure eyes, then you can work around it for flow.

I personally use this stuff and haven't encountered any problems with it.
