Time To Replace MP40 But With What?

[Madreefer]

Hey thanks to all for the resposes. I am going to keep running the other MP40 until it dies. Any opinions on the Tunze Turbelle Streams? I should have mentioned that i'm not all that concerned with a wave but more the flow. This is what my wife said to me today, "I just about slept in today, I always wake up when those pump thingies turn on in your tank". The tank is about 50ft from our bedroom. Theres a good example how loud the one that died was.
