Tunze 6101 noise vs Vortech noise
 

So I installed two vortech's yesterday, and one of them is a bit louder than the other, such that it's a little annoying. I'm pretty sure if I send that one back, they will say nothing is wrong with it, simply because it's just a higher pitch but not substantially louder.

Either way, these pumps are a bit noisy. The thing is, I've never had a pump that can do more than 1000gph, so I may be chasing a ghost.

How do the Tunze 6101's sound? For almost the same price (maybe cheaper), I can get two Tunze 6101's, magnet holders, and a multicontroller.

I'm considering switching if the Vortech noise isn't reduced. I can hear it down the hall in my room at night =(

how long have you had the Vortecs running ? Some take longer to break in and seat the bearings completely. But then again some are just noisier than others :(.

I've only had them since last night, so I guess it may not be totally broken in yet. But it does sound smooth, nothing intrinsically wrong sounding with the bearings, just a bit high pitched than the other. I'm thinking it's just a bit noisier. I may get another and use one in my frag tank, the noiser one =)

I jusst got a 2nd one yesterday and notice it seeming quieter and cooler compared to my older one. Perhaps theres differences in revision versions and you have 2 from different batches?

Ive never had Tunze's so I cant offer any comparisons. I notice the noise more when its on pulse mode. Its the ramping up part that gets the higher pitch. However, I prefer both on reef crest mode on antisync, which I do not notice a significant sound.

Mine is about 8 months old and doesn't make much noise... you are sure that it is aligned evenly? If it brand new can you bring/send it back to the place you got it from.

by looking it looks aligned, and moving it so it's unaligned makes a considerably louder / different noise.

I think I'll give it 2 more days, and if it doesn't quiet down I'll try to see if I can send it in or something =/

The reason you are hearing the noise is thet the motors are on the outside (reading the thread it occured to me) and Tunzes are inside of the tank, I can't hear a thing unless I press my ear to the glass-and I have three!

That's very true! Interesting =)

I'll have to visit someone's house who has the 6101's to listen to them... (with my dremel ;)

I have 2 vortechs and 1 is louder than the other. I sent the louder one back and they replaced the components (for free!:thumbsup: ) , but it still is louder than the other one. It's not so bad so I just live with it considering the overflows make more noise than the pumps. The flow is great and the undertow is amazing.

When I got my 2nd vortech it was substantially louder than the first at when it's 75% max power or so, however within a week though it's quieted down quite nicely.

I have 3 the new one seems to be the loudest however i thought the same thing when i got the 2nd one the WWD also makes it in Pulse mode because of the reving of the pump i switched all of mine reef crest mode and they are quieter

where did you folks got your Vortech from?

I cannot hear my Tunzes

I got mine from Ocean's Treasures in SF.

yeah in reef crest or lagoon it's much quieter without the ramping up and down. But the ramping is so awesome =)

they still ramp in Reef crest but it is much slower

I guarantee you that Vortechs are louder than the Tunze pumps. Vortechs are nice and they have some advantages over Tunze but I am personally surprised how loud they are. I was up at Johns store yourreef over the weekend and he had one running on his display. That motor had a nice high pitched hum to it. I then went to Atlantis today and he has one on one of his display tanks as well. Same hum. I don't think it is a big deal in a store but if you have your tank in your house and it is quiet in the house, I would get Tunze pumps. I have four pumps running currently and they are dead silent. The only noises I hear from my tanks are the chiller and some water trickling. As someone already mentioned the Tunzes are quieter simply because the motors are in the water.

I think I'll go with tunze 6101's instead. The vortech's are nice, but I don't think they're the best for my tank. My tank is so much quieter, and these vortech's are loud at the top end. I may keep them and move them to my frag tank, or sell them.

Darn, we could have traded. I have some Vortechs being delivered today to switch out my Tunzes.

Kinetic; I have 2 of the 6101's i do hear a bit of change in sound as they ramp up and down but the pumps are also brand new and i have only been running them sparingly on my new setup (tank is currently sitting in my garage with tap water in it to play around with the flow & controller options) so if they are anything like my 6025's were they will be even quitter after a little more break in time; I certainly can not hear the change in noise level if I'm about 2' away from the tank.

awesome, thanks for the help guys.

I think I'll have to hear these 6101's in person first to make sure the swap is worth it.

mcurl: oh that's too bad! let me know how the tunze's work out for you.

mcurl: do you like the vortechs better than the tunzes?

Yes, visually they are much better and they move more water. I use them with the Aquasurf mod.

I am almost ready to switch back to Tunze from the VTs. The ramping up/down noise when in pulse mode is just too much. We can hear it throughout the house (and it is an in-wall tank). It is not the motors, but the wet ends (and yes, they are aligned properly). Some are just louder than others. One of ours is dead quiet, but the other 3 are varying degrees of annoying. I am tempted to save up and put a pair of 6101 or 6201s in our tank to see how they sound.

I have heard that the VTs move more water than the Tunzes, but I can't say for sure since our Tunzes were on another tank, and the new tank was brought up with the VTs from day 1. Although the noise wasn't/isn't so bad so long as you don't change the speed too much or too fast (like pulse mode does.. *sigh*).

A buddy of mine has a single VT installed, and it's as quiet as ... his skimmer makes more noise.
