Sounds like maybe you need a new motor for it

Have you tried moving the unit around sometimes the motor rubs against the glass causing a lot of noise moving the unit a little bit might solve the issue

Clean the motor , run it in vinegar and water for a day or two.
Sometimes you can get a air bubble in the pump or a snail !
Maybe you can place filer material between where it touch's the glass. ?

Is it the motor or an air sound? I had the same skimmer on my fish only tank years ago and it was loud as well. It was an air sound. IMO I think those skimmers are junk.

I'd guess the impeller is wearing out and it's starting to rub in the block, the block or base is vibrating against the sump walls, or there is something banging around in the impeller housing (snail, small piece of GAC, etc).

I had one of these for a while as well. Noise has nothing to do with the pump, it's simply a very loud skimmer due to the way the bubbles are generated by venturi effect in the top of the skimmer. I could hear that sucker from most every room in my house, even with doors closed! I'm back to my old school, counter current, wooden air stone driven skimmer which is super quiet & skims better than I could ever get the Remora to.

If you search on the net, there are some workarounds which involve placing sound deadening material into the top of the skimmer to muffle the noise.

What kind of pump are you running? They generally come with a MaxiJet as the smaller pump option & a Mag 4 or something as the larger one. I had a Mag 4 which produced one heck of a lot of bubbles, but also a ton of noise in the process. I ended up cracking the inlet tube while trying to lift the skimmer off the tank for cleaning. That's the best thing that ever happened with that skimmer, 'cause it made be get rid of it & go back to my counter current job.

All remora skimmers are noisy due to its injector design. Here is a mod that will quieten it significantly.

Need:
-Plastic (I use #4, the lid off a cream cheese container)
-Air tube
-OPTIONAL Ė glue gun

Steps:

1) Take out the collection cup and dab it on a piece of paper, this will outline the aprox. size of the chamber as the 1st chamber is about the same size as the reaction chamber
2) Cut out the damp outline of the paper and stick it to your plastic, use it as an outline to cut out the plastic.
3) Take your air line hose and cut on one side across the whole length (which should be the total circumference of your plastic minus a little bit)
4) Cut the first to match the length of one side of your plastic, then cut 3 more according to how long you will need, you will need a little less then the total circumference as the with will take up some space on at least 2 sides.
5) Test the square with hoses around the edges for fit in the hole; you want it tight so it should bend a bit along its width, but not too much. Trim the length to fit and the width so that it will bend when in place.
6) OPTIONAL, I chose to use a glue gun to keep the air tube edges in place; I glued the top side only so that the glue wonít be in contact with the water as I donít know if it is harmful. If you make your lengthwise cut along the inside of where the tube naturally curls it will stay on without glue though.
7) Put it in place and clean it when you clean your skimmer

Ya its an air sound...super loud. The motor seems to be fine. I watched a youtube video from Remora and their machine was near silent. Maybe time for a Reef Octopus.

Cheers!!

** will look into the mod if it doesnt get thrown out the door..lol Thanks RDnanoguy!!**

I had one of these back in the day.

If you follow RDNanoGuy's instructions it'll help.

I folded up a blue towel (paper type from Canadian Tire) and stuffed the inlet chamber with it, not to the point where it would get wet though. This should deaden the sounds a whole bunch.

Remora also has a noise reduction sponge that they include with all new models and will send to you upon request completely free. I received mine a year or so ago and I have no problems with the noise now on my Remora Pro.

I have a black sponge on the left side chamber, is this what you are refering to?

I believe so it is the chamber that has the venturi injection that receives water from the pump. Initially they did not come with the sponge that has an indentation to allow you to fit it around the tube that has the spray nozzel. It was very loud for me before this but is not loud at all for me after adding it.
