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.

We engineered the DA-20 to be left in the water year-round. There's no need to remove it in the fall, clean and store it in winter, or re-install in the spring. Simply shut the DA-20 off, let it freeze in and forget about it until the spring thaw. Freezing conditions do no damage to the DA-20, even over the harshest winter.

This unit is produced with 70 feet of submersible, 12-gauge power cable. Greater lengths are also available, and special orders are never a problem. We manufacture a two- or four-light set that easily mounts within minutes; this can be added now or at a later date.

The DA-20 is proudly manufactured in the USA and carries an unconditional 5-year motor warranty.

This product is designed for use in either fresh or salt water. ARL tested and approved to be in compliance with the applicable requirements of UL and the National Electric Code as complete packages.
