black sand

Eh, Could be wrong on the maker, but it is the same stuff - there's a reason why the catalogue pictures they use for each (of the product, not the packaging) are identical.

Feel free to call the makers - whether it is carib-sea or seachem. I know we've been over this on a few of the planted tank boards, as many use onyx - but occasionally there are deals on the tahitian moon. It's been confirmed a few times that it is the same product.
