I've had Marco sand and while yes very nice, if you have fish that like to re-deposit, spit or move it with their tail you will end up with sand storms for a while until it matures.
After 14months mine never really stayed put so I swapped it out for a heavier grain.
I got my Fiji pink from unique aquaria at I think 11 dollars for 20 lbs of live sand. Also Mr. X we are setting the tank up Friday
