TUNZE Nanostream 6045 - Is it worth the hype?...

[skydancer]

I first bought the Nanostream 6025 a few weeks ago and overall I was pretty satisfied with it. It pumped quite a bit a water and was very quite. Based on that experience, I waited until the 6045 would come out and I received 2 6045s from Premium Aquatics' first shipment.

What a disappointment after only one week of use.
1) When they first come on they "rattle", and this is something the 6025 never did. But that's not a huge deal as I'm not overly annoyed by the noise. The fish don't like it though, as when the rattle starts they dash for the rocks to safety.

2) THE MAJOR ISSUE I HAVE WITH THE 6045 IS WITH THE WATER MOVEMENT. I know it is hard to believe, but putting the two pumps side by side, I can honestly tell you that the 6025 pumps MORE water (maybe twice as much) as either of the 6045s. Although it wasn't a scientific evaluation, I can confidently tell you that the 6025 blows on my hand twice as hard as either of the 6045.

I would like to hear Tunze response on this, as I spent $200+ for the two 6045, only to get less performance.

Has anyone else experienced such discrepancy?

Do both 6045's do this? Only a handful exist and they were handmade. I have had one come back that actually had a 230V coil and a 115V US plug, hence the slow speed and rattle. This is a defect, the few that exist were made from left over parts from prototypes to try to placate some of the early orderers. In general these pumps are better made because of the hand assembly and greater attention to detail but it does introduce human error and the possibility of putting a wrong coil/ cord combo together. I will gladly replace them for you and I think you will be very surprised by how much stronger the 6045 is, I won't have more though for a couple weeks, the main production of 6045 has just started in the last couple weeks.

Roger, I appreciate your comments on the 6045's. I have used many TUNSEs before and I know the products you put out are of the highest quality; and that's why I was so surprised.
To answer your question: yes both of my 6045s rattle and run on the slow speed. Definitely I would like to have them replaced. I don't mind waiting a couple of weeks until the "corrected" ones are available.

To tell you the truth, I wanted to buy a total of four 6045s but I could only get 2 from the Premium Aquatics' first order. Once I plugged them in, I had changed my mind and was going to go with the mjmods mj1200 option. So yeah, I would like to see the performance of the REAL 6045 before I make up my mind on purchase of the next two.

How do I go about the exchange? I'll pm you my Tel number and you can call me tomorrow anytime.
Thanks again Roger, and I certainly understand the growing pains of the early adapters...

I've a 6045 as well, my initial thought was these pump should be quiet like the 6000 that I got. It has been running for 6 days and still rattling. I read through the tunze forum and my thought was the rattling will go away after a few days after the break-in but till now, still the same. I've opened it up and checked the spindle, and it is still attached to the pump.

Peter,

Send me a PM and I will replace your drive unit with one that has a tighter fit and doesn't rattle.

Well now that I see this....I have a 6045 and my initial thought was that it dosent feel like its pumping as hard as my 6025. I feel the water comming out of the 6025 is stronger than the water comming out of the 6045. It dosent rattle, never has in the month or so that it has been running. Before going into the tank I had checked the shaft and it was nice and tight. Anyway to see if I have the correct drive unit or coil/plug combo Roger?

Without a watt meter the only way to tell is it often runs backwards, spins slow enough you can see the blade instead of just a blur and it has a weaker flow than a 6025. A watt meter will show 4w consumption instead of the normal 7.5-8W.

 

[Casino]

Well I have a watt meter. Where would I connect the meter to read the watts? I think I have a 4w if you say that I should notice a stronger flow than the 6025. Right now the 6025 seems stronger.

 

[rvitko]

A watt meter has a standard US outlet that you plug your pump into and it gives a digital read out. They also call them appliance analyzers.

While I think the constant delays with the nanostream line suck, they are great pumps. The main advantage they have in my view is size. The 6045s are roughly the size of a pool ball. You can stick them anywhere with the included magnet, and they pump out a fair bit of water. Im not sure it is as much as Tunze claims ... they are supposed to be 1100 or 1200 gph I think. My SEIO 1500 feels almost twice as strong as a 6045. I'd like to see what an independent third party test turned up.

I've got the SEIO 1500, two 6045s, my return and a maxi-jet in my 90 gallon and feel like the flow could be improved. Im thinking of adding a 6000.

Step on up to the big boys and get that 6000.

If your looking for large, gentle pulsing flow, then your on the right track.

Ok then I dont have a watt meter..I have a volt meter. So I guess as long as it dosent make any noise and dosent try to turn in reverse I have a good one...even tho my 6045 feels like it pumps less than my 6025?

 

[rvitko]

If it pumps less than a 6025 it has a problem, send it in and I will check it out and replace it if it is bad.

 

[emoutz]

Dont have a 6025 to compare to - but it does do better than one of my smaller SEIOs (that is rated around 600gph) and the propeller is moving fast (i.e. a blur, as you put it). Does the flow just not feel as strong, given the way the nanostreams are designed, as a SEIO, even though it is moving close to the same amount of wateR?

 

[rvitko]

The Seio produces more of a hollow tube of water, the force will be stronger because the center of the column has little flow, The Stream produces a solid cylinder of movement. I would expect the reach to be a bit less as a result.

 

[emoutz]

Makes sense. I figured the explanation must be something along these lines.

I know I have *****ed about the nanostream delays - but without getting into that - I also want to offer praise where it is due. The nanostream 6045 is a great pump. Silent, small, and moves a good bit of water.

I will wait to see when my LFS gets more of the 6045 in and compare them side by side. You must know him...John from Sea Creature Aquarium in North Providence RI. If it does turn out that mine is pumping less can I just switch them and he can send you mine? Im sure it will be ok with him, we would just need your OK.

 

[rvitko]

I would prefer to do this directly through me so I can verify the problem here.

 

[keinreis]

hate to beat this in the ground, but I must have 2 of the 6045's any idea of when the next wave of them is going to hit the stores, and do you expect there to be an abundant supply this time? I want to make sure I get 2 from this stock.

 

[rvitko]

I will try to get an answer on that next week.
