Over the weekend, my Hydor pump impeller broke, and I can't find any replacement. I have to get an emergency replacement. I settled on the Rio Hyperflow 14HF.
The pump works well, but there is an annoying hum. I am wondering if I should return it for something quieter. Can someone recommend a quiet return pump. I need around 700 gph
at 3-4'. Locally, I can get the Quiet one (3000 or 4000), or pay the big bucks & get a Mag 9.5.
