I just had my fire bowls hooked up which was the final construction piece in a long journey. Grand Effects 31" natural gas. Does anyone know if there is a specific lava rock that has to go in them? They put lava rock in there and it's fine but I was wondering how creative I can get down the road if I wanted to change color or the rock. Are there some types of rock that are better for flame than others? basically if anyone knows anything about them feel free to give feedback
