Help me identify this substrate pls

[ajremington68]

I have seen this type in other builds, as well as vik's tank and lou's tank over in the corner. It looks to be like very thick gravel, or almost crushed-up rock. Do we know a name for it so I can research to see if I want this in my 20-gal long build?

(starts at a shot of the substrate)
