Review on Enhance Your Aquarium with the Super Aquatic JVP-102A 1300Gph Circulation Pump: Efficient Wave Maker Power Head with Strong Suction Cup by Jason Selby

I don't understand the good reviews as there are serious flaws in the design of this pump. I didn't have a magnet but a suction cup. ok nothing wrong huh? Except that the knot holding the motor is capricious and not strong. The motor head probably weighs a good 2 pounds, so imagine weight affecting suction power over time. Not only that, the motor head was everywhere as he angrily pumped water at my fish, my rocks, sand, etc. and probably gave me a fish stick somewhere in his house. I need to find a wave machine that is midway up where it should be and not pointing at my fish and sand. Pooh!
