Blue Diamond Pumps Air Stone Round 8-inch

Blue Diamond Pumps Air Stone Round

The 8" round grey air stone with solid surround works with an air pump to create bubbles which add oxygen to the water of aquariums and hydroponic growing systems. 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.
