Pond One O₂ Plus 12000 — Replacement Diaphragm Kit

The genuine replacement diaphragm for the Pond One O₂ Plus 12000 air pump. If your pump has reduced airflow, is noisy, or has stopped delivering the usual output, a worn or torn diaphragm is the most common cause. This replacement part should restore it back to optimal performance.

  5. Reassemble and test: Put the housing back together, reconnect power, and confirm restored airflow.
