Query: pumps good (if you tolerate the noise!)

This review is easy to write:- pumps bubbles good- 'whisper' is misleading, because these pumps are very buzzy, noisy.I have 3- 27 gallon aquariums and 3 Whisper pumps. They are all the same, with the same noise problem. I am thinking of finding something less noisy and tossing these in the trash.My advice to the consumer is not to buy 'Whisper' pumps.Ask to try one out in the store - guess why they won't let you?
