lava gravel

The only concern is what the pH would be on it.

Make sure to rince it completely before doing anything with it.
 
lava rock/gravel should RAISE the pH, so i would do some testing in a bowl of water with it to see just how much of a rise it's going to give you before you toss it in a tank.
