As to expense, it's pretty cheap. I paid $30 for 50 pounds. 50 pounds of gravel at Wal Mart would have been $40. 50 pounds of Tahitian Moon Sand (also black) would have been at least $75.
The pictures show 50 pounds in a 55 gallon tank. It's about 3" deep everywhere. To clean it, you just hover the vacuum about 1/2" above the sand and suck up any poop or food. You can take your hands and kind of move the sand around to release any built up gas. I don't know if this is actually neccessary with the Color Quartz or not. I haven't experienced any gas bubbles building up in the Color Quartz like it does in real sand.
What else?
