A003 Bubble Stone, made of fine gravel that has been high-temperature sintered, has good air permeability and does not deform, making it an ideal decoration for aquariums. Connect one end of the bubble stone to an oxygen pump, and place the other end in the water. When the oxygen pump is turned on, countless small bubbles will emerge from the stone, creating a beautiful effect of bubbles floating to the surface.
