Hi, I recently got a new penguin 150B. I used to run a tiny whisper, and even though its filtering was lackadaisial (lack of room, poor flow rate, smallness, cheapnesss etc.) its pump was silent. Now this 150 can be heard from across my small bedroom, the motor hum. Its not anything extremely aggrivating, just a smooth low hum that can be heard somewhat far away. Is this what you all experience too? This is ssupposed to be an improvemment over the old series, wonder if anyone thinks its too loud? My tank is filled all the way.
