Blue Diamond - 6 in. Round Grey Airstone


The larger the surface area of the air stone, the greater number of bubbles, therefore providing fish and plants greater levels of oxygen in aquariums. When the bubbles aerate the water, they help to circulate nutrients in hydroponic systems to boost the growth of plants.

  • Use with an air pump and tubing
  • Can be used in hydroponic systems, fish tanks or ponds 
  • Distributes bubbles and raises oxygen levels in water
