Dome Airstone

The picture shows Dome airstones. The 10 inch dome takes an 8mm airline. The 6 inch dome takes either a 4mm or 6mm airline. 

The airstones are made from the highest quality materials which enable them to last a long time.

The fine make up of the Dome airstone allows it to create fine air bubbles which diffuse into the water more easily than large air bubbles. This helps beneficial bacteria to thrive to help with water quality.

IMPORTANT - This product requires an Air pump to run it. Not included. Also recommended are non-return/anti syphon valve to be insert into the airline near the air pump to stop water syphoning back to the pump.
