Smallest grade of white sand?

[bramjansen]

I bought this aquarium with sand, it was a very very fine grade, almost like a powder. I swear the guy said it was tahitian or haitian or something similar. What kind is this?!?! He said it was very expensive, but I love the way it made the tank look. Please, I need help. Google failed me.

oolitic aragonite.. a.k.a. southdown.

in case you're new, save your life and don't spend much time (at all) looking for the Southdown brand. It has become nigh-impossible to find anymore, under that name or Old Kastle. Good luck!

caribsea has oolitic sand. pricier than SD, but it still makes a great functional sandbed.
