I want to use MP40's, but...

You'd have to turn down the power on the pump that close to the sand though - maybe not if you used a bigger size, such as ReefFlakes.

I don't hear any noise out of mine. I don't use the pulse mode to create the wave though, which you do hear a little bit of a hum as it does its pulses. Have you made sure your spacer is set according to your glass thickness and you can also move the wetside around a bit if it's a vibration noise.

Either way, I love my Vortechs!
