Thanks for the replies guys.

I think I have been able to eliminate most of the direct vibration resulting from the pump touching the case. I bought a good size sponge, and cut out the shape of the pump, and half embedded the pump in the sponge. That seemed to reduced the hum significantly. But there is still vibration being transmitted to the case, probably both through the tubing, as well as simply through the air. If I put my case side back on (snug fit), the hum is restored in all its annoying glory because of the amplifying effect of the enclosed metal casing.

I am using 1/4" ID 3/8" OD tubing...pretty much my only option with the Innovatek kit. I bled out all the air, the Innovatek tank handles that nicely. Also put a little piece of that blue sponge that came with the Eheim into the tank to eliminate foaming.

So, assuming that I stick with the Innovatek blocks and tubing, what are my options here? Try a different pump? Same type?
Different capacity? Different brand?

Thx...
