Self-Weighted Air Diffusers
Award-winning EPDM membrane diffusers that sit on the pond bottom and release a fine bubble column. Self-weighted and fish-friendly — no anchoring — with the lowest back pressure on the market, so your air pump works less and lasts longer.

Fine bubbles
Precision I-slit membrane makes small bubbles that transfer more oxygen.
Self-closing pores
Slits open with airflow and close when off — resist clogging and tearing.

Weighted base stays put on the bottom; no stakes or blocks needed.
