The Savior 15,000 Gallon Pond Pump, Filter and Aerator System: The Savior can be for Koi Ponds, Fish Hatcheries, Lakes, Ponds and open bodies of water in need of aeration. Savior Aerator was made with the Aquaculture fish farm industry for farmed fish species like salmon, carp, tilapia, European seabass, catfish and cod. Also for the Aquaculture crustaceans industry like Shrimp farming. Save money and energy with the floating, solar-powered Savior 15,000 NCSFP20K pond pump, filter and aerator system from Natural Current, which runs silently from just the power of the sun. You'll be able to turn off your inefficient, noisy, and expensive-to-operate pool equipment and both reduce pollution and save money. The Savior eliminates thousands of pounds of pollution per year and it can pay for itself in as few as months not years. Its whisper technology makes it dramatically quieter than your current noisy pump equipment, and it requires less maintenance than your existing filter. Easily portable, the pump works in both sunny and cloudy weather--you don't need to live in an all-sun-all-the-time climate to reap the benefits of this solar-powered tool. (During periods of inclement weather, or for larger bodies of water, your existing pump can always be run for a few hours a day as a supplement to maintain water quality.) The Savior is powered by a two 60-watt, 12-volt policrystalline silicon solar panel made of tempered glass. The unit measures 34 x 65 x 12 inches (WxLxH) and weighs 45 pounds. The pool pump's solar panel has a life expectancy of 10 to 30 years, and you can expect to spend approximately $100 every 2 to 3 years on normal unit maintenance (including replacing the pump/motor and filter). It's backed by a 1-year limited warranty. Made in the USA
