 Just put a piece of foam rubber under it. I ran a mag9.5 for 5 years and it was silent with a pad under it, other wise the vibration goes through the glass bottom of the sump and can be loud. I had mine throttled down (discharge side only) for the five years with no issues, the new owner has no problems with it either. With a larger pump you can also tee off of the discharge and use the extra flow to run reactors or divert flow to a refugium, etc.
