Alas, I couldn't tell you the name, it was a couple years ago I tried this and I already had the sand in the house from another unrealted project.  I think the problem was that it was too fine of a paticle so the water was really murky and even after a week it never calmed down with the flow on (I was using a modded AC500 and a seio on that time) 
 
It almost seemed like the sand molecules bonded with the h20 and there were whispy clumps of sand constantly in the water.
