Round Airstones are oversized for maximum oxygenation of your nutrient reservoir.
These compressed silicate air diffusers simply connect the air stone to your air pump with tubing. The air pressure of the pump creates the aeration of the air stone that increases oxygen saturation.
Dimensions: Medium Air Stone - 2" x 2"
Large Air Stone - 2" x 4"
Connects to standard 1/4" tubing. Also works well in aquariums.
