PP Bubble Wall Air Stone for Aquariums 10"
These bubble wall air stones allow you to connect your air pump and create a wall of tiny bubbles in your aquarium,
The bubble walls can be used as a extension to add together or add onto any other size to create the size to suit your needs, They can also be cut to size.
Should the flow off bubbles slow down with time, this can be remedied by using a pin to open up the holes of the airstone once again.
