Tunze 6305 VS Ecotech MP60wES

[Daniel Reef]

It would be nice if someone who upload a video of the vortechs with the noise that they make. So often people upload videos of their tanks and then insert various music. so you never get to hear them unless you are there personally.

That is mine.

Also, I have used both pumps and there is no way I would choose a 6305 over a mp60. The mp60 is the best prop pump I have ever used hands down. I am swapping all my mp40 (5 of them) for mp60. The 6305 pumps I used had several problems and needed several trips back to tunze for repairs, needed zip ties to keep them from falling apart, and had shaft corrosion issues. The mp60 is a more solid pump with better flow.

Here is a chart off a recent study done by advanced aquarist. Tunze underperformed and has stated that their rated flow is in fact not correct but that they will fix it sometime in the next 6 months.

Thanks, but I couldn't actually differentiate sound of the pump itself with all the other noises that you indicated were in the background (reeflo dart, drain, skimmer, etc). But it doesn't appear to be significantly loud.

That was kind of the point. They are not very loud. At least mine are not. Start the video and listen at the beginning. You can only hear it when it is above 85% or so. Slight hum. There are 4 of the pumps running.

My gf thinks people who complain about the noise are obsessive compulsive. :lol:

Thats the point I've always try to make....take those other background noises away, and it will stick out more. I used to have a noisy tank with whirring fans, gurgling and splashing overflows, skimmers and pumps humming away.....until I found the total peacefulness of having a basement setup. I have a below tank sump, but use sound deadening foam, silent pumps, and Tunzes for complete silence. Every single other hobbyist that has come over my house comments on it immediately, how silent the display is. With the only thing making noise is the Vortech, it sticks out like a sore thumb even in the next room.

Call it OCD to want dead silence, but I think it is insanity to live with this gurgling, humming, whirring monstrosity sitting right in your living room. No thanks

Roger from Tunze has stated several times that the 6105 will have something available within the next 1-2 months, from roughly when the test was publsihed. The 6205 soon after, and the 6305 will take the longest, I believe he said by the end of the year for that pump.

I have no idea if they are still pursuing that, or if they are getting different tests done with different equipment, since several people have noted the potentail inaccuracy of the equipment used in the test from July.

I love the white noise my tank makes. Silence drives me crazy.

Also, shouldnt this thread by Mp60 v 6205? Given the flow numbers are nearly the same between the 6305 and 6205, why spend the money on the 6305?

Ummmm you can't hear the vortech during the day when other stuff is running so, that's a total non issue, and at night in night mode you can't hear it either especially over any small sound being made by your other equipment, so non issue again. People who talk about loud vortech's either owned one and didn't understand how to use it, or have never owned one.

If that's the case why would you use any power heads? Why would you plumb your tank with multiple returns from the basement to create all the flow you need with no pumps? It seems kinda silly to do all that work and then stick a bunch of tunze pumps in a display... or any pump really when you could achieve what you need to with pumps in your basement running at random intervals pushing different returns....

I would go vortech I run mp40 and mine isn't loud at all especially with everything else running. The broad flow and undertow is great. My lfs uses mp60 on the 240 square tanks and they are not loud at all. Never owned tunze so maybe I'm a little bias but from what I hear tunze is a great product also.

 

[Luxo]

Tunze all the way, Vortech's noise and also the wiring outside the tank is a show stopper for me.
They are not that loud but you do hear them. I had an MP-40 for a while but switched.
Never seen the MP-60 so can't comment on that.

Because powerheads use far less power and have better, controllable flow. I don't have to stick "a bunch" of Tunze pumps in there, just two. Plus with powerheads, there is that much less external as far as pumps, far less to go wrong, far less holes in the taks, etc.

Yeah, it is an issue. When other stuff is running on my tank, you cannot hear it. When I had Vortechs running on it, you could easily hear it in the next room 15+ feet away.

, and at night in night mode you can't hear it either especially over any small sound being made by your other equipment, so non issue again. People who talk about loud vortech's either owned one and didn't understand how to use it, or have never owned one.

This is the typical response given about the noise of Vortechs. First off, I have owned 3 of them ranging from the very first ones to the Gen2's. Great pumps, great flow and quality, and support is great. The motor is not submersed, so you can hear the motor whirring away. It has nothing to do with alignment, it is just the noise the dry side makes. That same noise would still be there if you held just the dryside in your hand.

Just because you cannot hear it over your tank, or don't mind the noise if you can....does not mean any other person that finds them noisy on their tank or wants a silent tank is doing something wrong or there is something wrong with them. If it is not an issue for you, great....it is for alot of people, just search for it.

Really? I need some white noise....I need a fan running to sleep, and an air conditioner while Im sleeping does not bug me much. Humming drives me insane. The whirring of the Vortech would not be that bad if it were steady, but every time it changes speed you can hear it.

There is alot of question about the flow of the Tunzes, and if the numberes provided by that test were reliable. There have been several people that have pointed out that the equipment used leaves alot room for error in the numbers. Hydrologist in the thread has used the equipment and is stating that.

I think taking one test that had the involvemnet of a competitor as the only test to base the flow rates on a little odd, but maybe that is just me. I think it is great to test these pumps. I do not think the large Tunze pumps are off as much as the test claims....I have seen them in my tank, and they move the tank greater than the Vortech. I'd like to see it explored more, but regardless, Tunze has stated they will correct the flow on the pumps whether they as short as the test states or even if it is half as much of what the test states. If we could all take a deep breath, maybe test the pumps some more, and see what Tunze does, I think it will come out as no big deal.

I have to agree with James on a many things, especially in tank powerheads vs the closed loop. Closed loops are nice because they are silent but with them you really have that many more holes in the tank and most CL pumps pull a ton of wattage. With a closed loops its much harder to resell a tank as well.

I have heard the Tunzes have had some problems with the magnets falling off as well but that it was on the original models, and both original models had shaft problems. Those are supposed to be fixed I believe. What is the maintenance like on both pumps, are there any parts that need to be replaced annually? I saw the Vortech bearing mod... great mod but I wonder why vortech doesn't have premium bearings on them already.
