Ceramic oxygen stone in form of a circle.
An oxygen stone gives a “jacuzzi effect” in your nutrient solution tank to help oxygenate the water and stir the solution around. You connect an air pump to the connection and the oxygen is pumped around. You can also put down the oxygen stone as it is without a pump and you still get bubbles with oxygen but they are not pumped around. You can help your plants with an extra good nutrient solution with an oxygen stone to get the best results for your cultivation.
Connectable to pump via a 4 mm tube.
Diameter: 73 mm.
NOTE! Hose suitable for pump with 6 mm connection
