Welcome to Canreef, Ross!
I do have some sand if you're interested, unfortunately I don't have a lot of sand left, not nearly enough to create a DSB in a 180, but, I can for sure get you hooked up with something. This stuff is primo white sand, very fine grade. (Similar to Caribea "oolitic" or whatever they call it.) I was going to use some of it for my new tank, but, I can get you set up with something for sure. $25 per 30lbs.
Give me a call if you're interested, and we'll figure this out.
(Maybe another pallet needs to be brought in!!! Aaargggh, maybe someone else can store it if we ever do this again.
