What do people use for black Substrate in a marine tank?

[Papou]

Black sand from Hawaii ?

I once watch a documentary which had a really interesting part about "Volcanic" reefs where the sand was all black. Soon after I set up a 40g breeder using Tahitian Moon Sand. It's not aragonite based but I always found the natural carbonate buffers in the salt kept my chem stable! Good luck!

Thank you for the awesome suggestion.  I am going to contact the local LFS's to see if any of them carry this product in stock.

I think any inert sand will do, I just chose that one because the store I worked for had it for cheap It was "SUPER NATURALS", I think it will be common in most stores with freshwater fish.

Looked around a bit for you, apparently Carib Sea now carries the SUPER NATURALS label (maybe they always did?). Should be available pretty easily.
