“Alumina” air stones – three times stronger than white silica air stones! Produces a finer bubble with no increase in pressure.
Inlet fittings are set into the body of the diffuser, making them much less likely to break or twist loose.
All are 1 1/2" X 1 1/2" Square
Available in 3, 6 or 12 inch lengths.
