The DA-20 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. Stainless steel, oil-free submersible motor is low-maintenance and environmentally friendly Easy to install, just two tethers or anchor ropes with weights (not included) Can be left in the pond during winter, just shut it off and let it freeze! Requires GFCI, and should be disconnected when swimmers are present Designed for 24-hour operation or with timer Can be used in freshwater or saltwater Manufactured in the USA, with a 5-year motor warranty Size 1/3hp 1/2hp 3/4hp 1hp 1-1/2hp 2hp 3hp Voltage 115V230V 115V 115V230V 115V230V 230V 230V 230V Watts 670 680 — 12 1780 2280 3000 Amps 8 10/5 — 11.5/8.2 10.6 12 13.5 Flow Rate 300gpm 400gpm 450gpm 500gpm 600gpm 700gpm 800gpm Pond Size 3/4 acre max. 1/8 acre min. — Pond Depth 32" min. 36" min. 38" min. 42" min. 38" min.
