Thanks for your input.

I’ve used Eheim, Ocean Runner, Sedra, AquaBee, Octo, etc. While I have not used the 9000HO, the brief experience I have with the WM Sedra 7000 it is not that much louder than an Eheim 1260. I feel this is largely due to the silencer and uniseals to eliminate vibration. It’s quiet enough that I would put in our system that is only a partial wall and 10ft away from my bed… and I am truly as picky as they come.

In my experience, Eheim 1260/2s are really not all that quiet when used as a NW. If you truly want quiet, talk to Klaus

Also keep in mind, most Eheim powered skimmers are quite expensive (Warner also has Eheim models), this is a nice alternative as everyone’s situation and application is different.

If you have the opportunity, check one out in person.

But after you lived with a Sedra and an Eheim on a skimmer, as far as noise, vibration and durability, there is no “run for the money”. Eheim leaves Sedra in the dust…

I find it so funny that reefers work diligently to quiet the overflow, quiet this, quiet that–but then they live with the vibrating manifesto that Sedras are…
