There are black beaches and reefs and they all have sand burrowers. I wonder given enough time the black sand is filed down to make it safe for them.
@Brew12 that’s some really cool stuff.
The stuff I have is 2mm-5mm, at least. The Tahitian was 0.5mm max. Super fine and awesome for sand burrowers. Just full of metals.
