H-Series Glass Oxygen Diffuser
This is a small air stone with a larger glass surround, the idea is to create air inside the glass chamber which will then release air slowly into the aquarium, This prevents a couple of things, if you don't like bubbles flying around the aquarium it stops this. the other thing it prevents is bubbles breaking on the surface which can cause spitting an become a bit of a nuisance on a lidded aquarium.
kit comes with: glass diffuser, air stone, x2 suction cups
Compatible with 6 mm (1/4") - Standard Airline Tubing.
Any air pump is compatible with this products, we highly recommend the Oase Oxymax range as we find it to be one of the most quiet air pumps available
