I'm going to hear this one out (pun intended). I have a Vortech MP40 collecting dust because it's so noisy. One of my clients has one that's very quiet though, not sure what the difference is. I'm interested to see what everyone says about the QD in the upcoming weeks.

Ordered mine last night. I will do an upgrade thread and possibly a noise test of both.

I've had my mp40 qd since they came out and I'm pleased. 100% short pulse mode with the fastest pulsing and I can only start to hear it from 6 inches away putting my ear up to it. Standing 3' away in front of the tank and I hear nothing.

Please do!

That's amazing! I hope you're not doing this in a room with one or more children sharing the space as that will significantly skew your findings.

With just the tank running was how I tested the noise level. These upgrades are the real deal. Also realy like how the new 40 wetsides are built the same as the mp10 wetsides. Durability should be good too. Future talk on these pumps won't invole talk about noise.
