The simple, budget-right diffuser for windmill and small-pond aeration: a self-sinking airstone that throws thousands of fine bubbles, with a foot valve for one-way airflow. No anchoring hardware or tools needed. Choose a single, or the double pack with a ½" two-way selector valve for two-zone aeration.
