Greg, here's what I'm look for to use as the substrate in my 75 gal.

CaribSea oolitic select. I'm not sure if Drs. Foster and Smith carry this brand, but see what you can get for oolitic aragamax substrates. Ideally, I'd like three bags of this for a total of 90lbs.
Let me know what you can get. I'm looking for the oolitic grain size, .5-1mm like this sand.
Thanks for checking, Greg,
Joe
p.s. This won't be needed for a while, but I'd just like to know now what you're capable of getting for me in the future. Thanks! Hope the candy cane frags are opening up well for you by now.
