Sand, so confusing. Help!

[Fishingandreefing]

So the more I read, the more confuses me and I can’t remember what kind of live sand I ordered Almost 4 years ago for my current 120.

I need sand for my reefer 350 as the old sand I cleaned has magnetic sand or particles in there. It might ore which pretty common but I just want to make sure there are no metal rust in the sand.

I need sand that is suitable for gobies but not too fine that blows around. Please see attached picture is the sand I want.

can you guy suggest which sand is close to it?

Or if I go through the old sand that I cleaned with a n52 magnet, would it be safe to use?

Caribsea special grade. It's larger granule size than normal and it's a perfect size that doesn't blow around easy, yet is suitable for all sand sifters and burrowers. Love it.
