Review on Efficient Aeration with Eheim Air Pump 400 by Jamie Mason

I have had several air pumps over the years, most of them Tetra Whispers. When I heard it was the quietest on the market, even quieter than a tetra, I wanted to try it. I bought one to put in the kitchen for my betta tank. That thing is SO LOUD. i hear it on tv It rumbles and the rumble is so incredibly loud. I have it on the lowest level. It was ok at first, but seriously, no more than 2 weeks at a time and it was just unbearably loud. I've already lost count of the number of times I've said that word out loud in this review. I don't know if mine is defective but I hate it.
