You are basically trying to find a happy position between where the end of the tube meets the flow control piece.

I have also found with mine (I have it for 7+ years now) getting noisy after a thorough cleaning where I pull the whole filter and bleach soak it. It seems to rattle a bit until some new gunk builds up in the impeller area- kind of a natural, slimey lubricant.
I could add in some mulm gunk from another filter . . .

Sounds like you're all on the money. However, now that They don't wan't me back, I sure as hmml ain't gonna put out another penny on this school--I've spent close to a thousand bucks on books, extra materials, candy bribes, extra time and energy and heartache, and additional gas, and I've had it. I put one of my dual Whispers on it--I can just leave that and tell the principal the Emperor is shot. So, thank you all very much for your input, I've learned alot as always and greatly appreciate it. Happy trails, Renee
