are you sure you have lava rock? normally lava rock is hard and sharp with lots of tiny holes.

just try boiling it for 5 mins, and left it to cool for few days. change the water if the rock still clouds the water. if the problem remains. throw the rock.

Usually if you wash the lava rock, small fragment of the rock will disintegrate. As for the black water, maybe it's coming for the dirt as accumulated on the lava rock. Rinse and soak the rock till the water become clear will do.
