Performance and use: delivers an air output of 0.8 L/min while producing less than 60 decibels of noise. Setup is simple: attach the included 150cm air hose to the pump and connect the bubble stone, place the stone in the water and the round aerator will float and begin working. Ideal for boosting oxygen in small family ponds or localized sections of a pond; energy-efficient and environmentally friendly.
