Review on Hydor Seltz D DC Controllable Universal Pump for Aquariums, Reefs, 🐠 Ponds, Turtles, Terrariums, and Fountains - 500 GPH, 750 GPH, and 1000 GPH by Monica West

It was easy to hook up to my system and has worked flawlessly for the past few weeks or so. The controls work well and the feed break option is handy. At a maximum of 1000 gph, it works quietly. If you're just planning to max it out, it's pretty low noise, but if you dial it down, the noise increases. The lower it is, the quieter it should be, but it's not. This is a good value for a DC reversing pump.
