This rubber membrane is a replacement for all KA models (KA Mini, KA 1, and KA 2). Please note that this is the rubber membrane only -- not the ceramic aerator diffuser stick. Membrane covers should be replaced as needed when algae and other debris clog the membrane pores. You'll know when it's time to replace the membrane when there is little to no air coming from the aerator diffuser.
