Bests & Worsts Reviews from Amazon

For all of you that have this pump and say it makes alot of noise...Oh you are so so right....Here is the simple easy fix to it....As you see in the picture and video take the 4 screws out of the bottom side and take the cover off...This will expose the 2 diaphragm...You will see 2 arms that conect to the diaphragms...There are magnets at the end of those arms,one or both of them is hitting the reversed polarity magnet and making that noise...All you have to do is get a small screwdriver and bend that arm back toward the diaphragm just a bit to give clearance for it to cycle back and forth...
