I just got a QP-5 from Coral Box [for my 14 gallon]. It's very, very quiet and very powerful. I have no information on longevity, though.

Thanks ThunderGoose. I guess they don't have any electronics embedded into the motor block like the WP and RW series pumps do. I had a couple WP-40 pumps that only lasted a little over a year, then sudden death. I had them on wave mode switching from full on to off a couple times a second 24/7. It's definitely the motor and the impeller assembly seems fine. I'm sure an electronic part embedded in the epoxy motor block failed. It just twitches one time when I give it power.
The wave thing seems like it was a passing fad, probably in large part because so much switching is hard on motors.
Anyone else using a QP pump willing to give the good the bad and the ugly?

Been running two qp5s for about five months. No problems. Quiet. One noticeably reduced flow when it got dirty but cleaning restored the power. I just run the smooth ramping up and down but at slightly different intervals. I prefer this configuration over any of the linked modes.

Been running the qp-9 and love it and it’s power. I did do some research and they have made a controller for these to be able to connect to WiFi and Phone. The bad part is you need a controller for each pump and can’t connect more than one pump to a single controller.
