[Delphinus]

You may be in luck ...

I am about a week or two away from finally getting my 50g taken down. When it's finally empty, the sand will be available to any who wants some.

Here is the catch. This is grey "plenum grade" aragonite, so the granules are about 1mm to 2mm, so it's not a "pretty" sand by any stretch.

But, it's been in my reef tank for five years now....

I am not ready yet, although I guess a scoop could be taken out of there now without too much harm (just not too much, because until the tank is empty I still need it..)
