Review on PERSUPER Aquarium Output Aerator Valves by Patricia Dworin

I live in a small house. Couldn't get rid of the noise. Finally, fold the towel in half, place a thick mold block on top, and then place the pump inside the double-folded pillow on top of the styrofoam. Works like a clock - the noise is gone. The pump is very powerful. OK. After writing the above review I've had more time with this thing. I wear hearing aids (wife says I'm deaf even with them) and it's driving me crazy. You definitely do NOT want this in a room where you need quiet. I tend to throw it out the window. THIS IS NOT QJIET.! This is a good pump but be careful. Put it in another room where you don't want to spend time.
