Pond Aeration Diffusers

Pond Aeration Diffusers

Diffusers are the business end of an aeration system — they break the air stream from the pump into fine bubbles that dissolve oxygen efficiently into the water. Play It Koi carries air stones, disc diffusers, membrane diffusers, and diffuser rings from Matala, Alita, EasyPro, and other brands.

Diffuser Selection Guide

Fine-bubble diffusers transfer oxygen more efficiently than coarse-bubble models because smaller bubbles have more surface area per volume of air. Membrane diffusers produce the finest bubbles. Place diffusers at the deepest point of the pond for maximum circulation and oxygen transfer. Pro tip: weighted diffusers or those attached to a base plate stay in place better than loose air stones, which tend to shift and float in deeper ponds.
