Preweighted Koi Pond Diffuser

Preweighted Koi Pond Diffuser

Product Code: OB1

Regular price $69.00 $44.00 Sale

This diffuser features a unique micro-porous membrane that keeps fine bubbles from coalescing into bigger bubbles. This feature greatly increases the amount of water that these diffusers can move, which means much better aeration.

Airflow rates of .375 TO 1.125 CFM are recommended for the OB1 Diffuser, but they can handle more than 3 times that much. Diffuser comes with a 1/2" NPT Female PVC connection. We recommend using a check valve to prevent lines from filling with water if used for winter aeration. This diffuser is self-weighted and sits upright on the pond bottom.
