Is the black sand safe tho, I added some to my old reef tank years back and one day my cleaning magnet fell into the sand and when I picked it up there was a bunch of iron flake stuck to it. I researched the volcanic sand and it was very high in lead and iron content-not so good for a closed system.
Hopefully yours is reef safe because it looks fantastic!
