I have seen some videos on youtube with some people complaining that their spouses are just not happy. What are peoples thoughts on this? is that one of their drawbacks??

let me know.

I have 6 on my tanks 4 40's 2 10's, feel free to come out or stop at a store with ur spouse and see if they can handle the noise.

You should change your signature to 4 mp40s.

Dear Blue Tang,

Do you have a store in spruce grove? Im in edmonton and I would love to come by and check out the tank.

I have two and I find them loud, I can hear them now with the tv on

I find that when I leave for work I crank them right up and when I get home I turn them down.

I do find that they work great

I have two MP10wES... My older one is loud enough that it whines when upstairs but I bumped it a little while ago and I dont think I lined it up correctly when I set it up again, because my newer one is only half as loud. I can definitely hear them in the next room though, they are on 100%... it was a bit annoying at first, but I have good ears and low 'annoying noise threshold' lol. It doesn't annoy my folks who hate annoying noises (like the smallest water drip or pump humming), though. Its not obnoxious like loud droning, but its defintely an audible 'whir' as it winds up and down.

Cheers,

Chris

Marine Aquaria, BigAls, & Redcoral. They have mp40s in their tanks.
I have 2 MP60 in 1 tank, and 1 mp40 in the other. If you want to see it PM me.

Aquarium Illusions also has one in their display tank.

In person at a house is probably best thing though for comparison... because stores are umpteen times louder than homes even without people in them.

If you buy used and they are out of warranty and you consider yourself as a skilled tinkerer, there is a thread on RC that goes over replacing the bearings on them to quiet them down. Buy some really good high quality RC bearings from Boca. You'll need a couple tools and a bearing puller to do it without damaging anything.

I have the bearings downstairs for my 1.5 yr old MP40, I just need a bearing puller and then I can do the replacement.

If you do decide to do this, just don't use a screwdriver to pry off the bearings as it will for sure break the magnet.

No guarantees on how much quieter this will make them though.



P.S. In theory you shouldn't need to do this as the product should be engineered to be quiet. But as we all know, they slightly lack in this area...

I personally don't mind the sound, it sounds like a symphony!!!
