Pond One Diaphragm for O2 Plus 12000 Air Pump restores lost airflow by replacing the worn moving membrane inside the O2 Plus blower, ensuring strong, reliable aeration performance again. Replacing the diaphragm together with the flapper valve and housings (sold separately) is recommended for peak output and longevity.
