Buy a Spare Oxygenator Air Stone, Fits 4 - 6 mm Tubing and Provides a Clear Diffused Path for Blocked Air Stones Best prices, Great Reviews, Free UK Delivery
Our Handy Spare Air Stone Accessory Fits nearly every air stone on the market, all Powerbee Oxygenator models and all models that support 4 - 6 mm tubing, which is pretty much every solar brand on the market, but please check the tubing.
Simple - just pull the old air stone out of the tubing and pop in a new one, air stones do become blocked especially over the winter time when they can be sitting in dead leaves for prolonged periods of time, you can try cleaning them out, however this can be a bit hit and miss and usually it is easier and more straight forward to replace the old one.
