Air Stone Kit
This glass-bonded silica air diffuser has 140 micron (0.0055") pores which will create bubbles of 1 - 3 mm in diameter. Use with 3/4" ID tubing to connect to one of the outdoor air pumps.
Stone measures 9" L x 1½"W (23cm X 4cm) and weighs 1.35 lbs.
Kit includes two silicone rubber "bumpers" to protect the stone from damage and to maximize air flow beneath the stone. (bumpers shown with smaller stone)
Air Pump and Tubing are required and sold separately. Clamps are recommended and sold separately.
