Air Stone (Carborundum)

The air stone diffuses a stream of tiny micro-bubbles, creating a dynamic visual effect and aids strongly in oxygenation. This is done when air is forced through it via air pumps or submersible pumps. As the air stone starts to slow down, this eventually means that they are clogged and when this happens, washing or changing them would do great. It works the exact same way as air bars does.
