i would put in a support ticket and ask for a new venturi. sounds like the straight taper into the body may not be so straight and you could be getting some rattling against the body. if you want to see if it rattles, pull off the cup and airline from the venturi and just let it overflow while listening for rattling. if it's rattling against the body you should still hear it w/o the air draw. post a video too that may help with any further suggestions
wow, not much room between the sock trays, weirs and returns in there?
I don’t think its the pump anymore. When i run just the pump i can’t hear this particular noise. In fact if i put the skimmer body on without fastening the screws (so it just rests gently on the baseplate) then there is not this noise. On the other hand there is a lot less bubbles because a lot of water goes out between the body and baseplate. There is no silicone seal between the body and baseplate, its just acrylic on plastic so im at a bit of a loss as to what to do herethanks
pump body looks fine and no cracks. the ceramic bearing shaft looks fine too. does the primary needle wheel look free from snails, pin bends or missing pins like in the attached pic below? Also does the secondary stationary pin insert on the volute look bent up or missing and pins? check to see if the stationary pin inserts have any play or are loose. if they are, they may contribute to some rattling. If all looks fine then re-assemble and run the pump (only) in a bucket of salt water unattached from the skimmer to see if you hear anything that sounds off. you will hear a lot of air draw if you dont connect the silencer and that may mask any other noises you are looking for so if you can keep that connected.
Hmm? If there's enough thread in the set screws that hold the body to the base plate you may be able to try some thin silicone sheeting and cut it like a gasket between the base and body. You would need to pad it under the pump too to raise the pump to the same level so the venturis would line up to the holes on each side of the body. May be worth a try and you wouldn't be cutting anything. Heres some thin material to consider.
Good idea but i don’t think it would work with the way the twisting screws are made on this skimmer. There is probably not enough space to add 1 mm of silicone

bummer. i didn't realize these had that 1/2 turn butterfly screws. I would still try silicone. they make even thinner sheets down to 0.1mm. something to consider
as long as the gate valve is wide open just let it run. common since there are production residues still present, even with deep cleanings. these residues play with the surface tension of the bubbles. how old is the system? your sump looks pretty cleanExtreme overflow with new skimmer. I have a reef octopus on my red sea reefer 350 g2, cycle is underway currently, sump water level is exactly within manufacturer parameters (8.5 inches approx), flow valve is fully open, but the bubbles are still causing water to overflow to rapidly to even seal the skimmer cup (I’d have to empty it every 30 seconds). Is this just a break in period? It’s been running for a few days now. Video below. Any tips?

Thanks - will just let it keep running as is then. I set up the tank about 3 weeks agoas long as the gate valve is wide open just let it run. common since there are production residues still present, even with deep cleanings. these residues play with the surface tension of the bubbles. how old is the system? your sump looks pretty clean
should be no problem running a life reef externally. they are not subject to the matching gph throughput/height/depth that needle wheel skimmers have. they are old school countercurrent skimmers with mazzei style injectors. you can feed them from anywhere as long as you have enough pump and can get the effluent back into the sump with no restrictions.
OMG. That's the exact sound my Reef Octopus Elite 200 does since day 1. Its been a year and I have not found a solution. I had contacted Coral Vue and they wanted me to send the pump in and pay 1 way shipping on a brand new skimmer and likely give me a remanufactured pump. BRS would not take it back so I learned to live with it. But when I do take the skimmer out to clean it becomes dead silent but then gets loud in a few days. I don't believe what we are hearing is the pump. I can run the pump underwater with no tubbing and it is silent. What I hear is the pump chopping all the air. I have tried bypassing the silencer and running it straight into my CO2 reactor and the sound continues. I can hear it coming from the skimmer. The impeller magnet does get like a nice coat of slime on it and when I clean that off the noise magically goes away but like I said it comes back. And the noise was present when the skimmer was first installed into service brand new. I must be cleaning something else or something isn't right with the skimmer venturi. My kids call my skimmer the popcorn maker.Since a few days i am having this really strange popping noise from my skimmer.
I have tried dissembling and cleaning it and i have also tried cleaning the airline tubing with very hot water to dissolve any salt buildup. Neither made any difference.
anyone know what it might be? Right now im stumped as to what to try.

you probably can find some nesting boxes on amazon that would fit your needed dimensions.
The three skimmers i use in my rotation all have loud air draws which make the sound like you describe if not connected to a silencer or my CO2 reactor. My CO2 reactor has two stages which makes the air intake silent. I ran a single BRS chamber and it was still loud so i had an old RO/DO unit in the garage and decided to run 2 of the cannisters in line to the skimmer. The first chamber 1/2 full of water and the second chamber with the media. The water in the first chamber helps keeps the air moist into the media chamber and the added plus is that it knocks out the air draw noise.
That skimmer should not be overflowing like that. Even while its "breaking in". Make sure the gate valve is fully open (counter clockwise) Make sure the gate valve is working by opening and closing and see if the level in the skimmer goes up and down. You don't have any medications or media or anything else in the water that could make that skimmer go nuts. Try dropping the water to 7' or even raising the skimmer itself. I know sometimes skimmers go crazy in the beginning but that just looks a little extreme.Extreme overflow with new skimmer.
