Hi Jon, I'm using Onyx sand in a 20g and it is working fine. It has
a variable coarsness, from almost dusty to about .10 inches dia. The
particles are very sharp, probably not too healthy for cories or other
whiskered cats. I mixed it with black jungle gravel and it stays
fairly blended.

Thanks Steve, that's the sort of info you don't get from an online store
Have you been pleased with the results, from a "plant-growth" point of view?
