Little Giant 4MDQX-SC (aka "the Gas Turbine")

[AJ_77]

Started using this pump on a 90g with 33g sump. Are there any other owners out there who can advise as to dampening the overwhelming sound of this unit? It sounds like I'm having my furnace cleaned.

I tried throttling back the flow with ball valves on the returns, but it was worse. It likes to run free.

With my ear to the glass, I can't imagine any creature wanting to live with the vibration and noise.

Suggestions? Other than the "Buy/Sell" forum?
