This DA-20 moves 400 gallons of water per minute in a cascading, trumpet-shaped spray pattern, approximately 6½ feet tall by 22 feet wide.

This flow rate does a fantastic job moving algae off of the surface, maintaining clean and clear water, and keeping pesky insects away, all while adding a large amount of oxygen to the pond. Adding oxygen does wonders for your fish, and is the key component in rapidly breaking down decaying matter at the bottom of your pond. As an added benefit, more oxygen means less muck over time.

The DA-20 is manufactured utilizing a stainless steel, oil-free submersible motor, making it the most environmentally friendly water aerator on the market. You won't have to add or change oil, no other maintenance is needed, and no control box is required.

The DA-20 is also simple to install, requiring just two anchoring ropes and weights or tethers.
