Wish I hadn't now. It's the noisiest pump I have ever had. Really makes a racket and it's been in the tank 1 day. I'm thinking of cutting my losses and throwing the thing in the bin it's that noisy.

Where did you get it? Can't you return it?

I had WP 40 pumps and ran them in wave mode going from full on to off a couple times a second 24/7. They died suddenly after a little over a year. I'm sure it was some electronic part imbedded in the epoxy motor block. Fishstreet was real good about sending new motor blocks.

It seems like wave mode was a passing phase, probably in no small part because so much off and on is hard on motors.

They say the QP series have no electronics in motor the block, a needed improvement, IMO.

The German engineering thing seems like a load to me but IDK...

So I was thinking about trying the QP but so far it looks like a 50% failure rate, could that be typical?
