So this just poped into my head tonight at work. I want to make a cave for the center back of my tank. Has any one tryed making a PVC cave out of like 1/4 inch PVC pipe and drilling small holes into it and runing a pump to the PVC like a spray bar. I was thinking 2 pumps and alot of holes. With rock all around it trying to hide all the pipe.
