Hello to all.... I just turn on the same skimmer Chris and yes it is a jet liner, you can hear the noise from upstairs. I will try a dB meter to find out how much noise it makes.
By the way, what about the silencer to made, did it work as planned?
This is the first Reef Octupus I buy and the last one...
Thanks
Juan Suarez
P.S. I wished I read your issue before my buy.
