You're problem may be two-fold.... the sand may not be dried, try a lumber
yard for blasting sand, I pay 5 or 6 bucks for a 100lb bag, either 30 or 40
mesh.
The other problem may be too much moisture in the air, you should have a
water seperator a minimum of 30 feet from the tank, the farther the better.
There are also other more expensive options (think they're called
collescating filters?) but they get kinda pricy.
