I wish I could find a supplier of that substrate :-)

Auburn Aquariums sell the finer black gravel; no more expensive than normal
stuff. I found it after running all over Sydney trying to get enough for
myself when I dropped in to get some ottos (which no one had at the time);
for some reason everyone assumed I had algae problems...

Cheers,
