yeah, that's what my HD has "Kolor scape" this is silca sand. It states this on the front bottom right of the bag.. as a matter of fact it also states that silca inhaled in a known carcinogen.... :eek1:

It looks just like Southdown as far as being very fine and pure white. Very easy to be confused.

I know, the thing of it saying not to use on aquariums, really scares me.
Has anyone done the vinegar test to this sand?
