Vortech Killer?!?!?!

I bought 3 at the BRS frag swap and find them very noisy as well, I can not run them on pulse mode which is my preferred mode and be able to enjoy the tank. I run them on reef crest mode at about 80% and I would say they are about as loud as the jebao's I was running.
I did contact reefbreeders and they sent me new bushings and impeller assembly but really no different. I was almost wondering if it's the thickness of the glass, I have these on the back wall of a redsea reefer 450 and that is some thick glass, the magnet has so far held them in place but not very strongly and thinking this could contribute to the noise. Do you have thick glass as well?
I am still running them because they move a lot of water, the flow is very dispersed and the three linked up in Slave master mode with no issues. I also like the feed options of either 10 or 20 minutes depending on which feed button you press and they have a reverse mode that is great for cleaning the gunk off the guards as well as stirring up the stuff on the sand bed right below the pumps.

I don't believe it's glass thickness, I've got a 40gallon breeder and the pump is very loud.

I think the main issue here is that they’re not MP40’s...

My tunze is way quieter than my old mp10

They're not mp40s, with that said I'd probably never waste my money on mp's ever again. These pumps may be noisy but for the price and the way they move water around, in my opinion it's a no brainer.

I just got home and damn this thing is loud. I'm starting to think I got a lemon because it sounds like a Honda civic with no oil in it. I can hear it knocking and a squeeking noise from the impeller.

The bottom ceramic baring may need to reseated.

Yeah I just pulled it apart, it must've sucked up some gunk, I cleaned it and reseated it and it's much quieter... but still noisy though lol I'm gonna buy a few of these just in case I upgrade or need a spare.

Check both ceramic barings, the one on the cap too.
