The other distinct advantage of a stainless steel diffuser is the ceramic discs are replacable if required. As algae forms on the surface of the ceramic disc it clogs up the pores resulting in larger less effective bubbles being formed. When this happens there is less surface area of gas in contact with water therefore reducing the rate of absorbtion. However when algae builds on a stainless steel diffuser simply unscrew the cap, flip the diffuser over and it works like new again.
