Simplicity DC Pumps have lately emerged as one of the most reliable return pumps on the market. Little was known about this company until a couple of years ago when it seemed that their full line of products began receiving more and more acclaim. These pumps come with an industry-best 3-year warranty which means they really stand behind their products and believe in what they sell. Each pump comes with a DC controller to finely tune the flow rate that you need as well as a designated timer setting for feeding your tank. These features coupled with exceptionally quiet operation is why even most of us use Simplicity DC pumps on our home aquariums. We believe Simplicity is here to stay as they continue to contribute to the aquarium industry with their innovative products and outstanding customer service.
