Hi Josh,and welcome to the board.
I am using something a little different. I choose put in my tank a 6" bed of glass shot peen with about 1" of Oolite on top with some rubble patches. The shot peen is just glass marbles with sizes that range from sugar to silt - $20 for 44lbs. Looks white just like Oolite.
You can look at the specs for the shot peen at this site. They are located in town (Calgary).

I am still early into the trial of this type of media so proceed at your own risk. So far, so good. :D
A suggestion that I made on another post was to put your Oolite Sand around the perimeter of your tank. Fill the centre with the lower cost play sand and then top it off with Oolite. You get the good looks of Oolite with the economy of play sand. I am going to try this on my next tank.
