Laguna Max-Flo 1350 GPH Electronic Waterfall & Pond Filter Pump - For Ponds Up to 2700 Gallons - Ideal for Waterfalls, Fountains & Aquatic Gardens

This is hands down the best pump I have used for my application, which is a notoriously difficult one: ducks. I have two Peking ducks that produce a LOT of waste into the 4' x 4' pond they are in, and this little pump takes on that challenge like a champion. Continues to work regardless of the work load it is exposed to.Maintenance is a breeze, there are four yellow plastic screws that hold the outer shell together (which does a great job of keeping things out of the propeller of the pump). I wish they were made of stainless steel, because I have to be very careful as to not strip them with a metal flat head screwdriver. Regardless, the pump comes out of the shell and separates into several easy-to-clean parts, and is easily reassembled.This pump really does check all the boxes of a great design, minus the shell screws. I would recommend spending the additional money on this pump in order to save the money of replacing the cheaper ones, and fighting with trying to maintain them as well.
