Tunze Stream 2 performance and build quality

BUILD

My first impression about the design of tunze stream 2 wasn't good because I thought it going to be a cheap design. But all that thought change immediately after i open the box of the Tunze 6085.

The pump look solid with lots of open area for water intake

The intake screen did not have the lip where most of us reefer think it will restrict the flow

The magnet holder is 1/3 of the size of the original magnet holder but twice as large as the nano stream magnet.

The impeller is one piece with the addition of tunze titanium alloy shaft

The C clamps is super strong I try to pull it apart to see if it is going to break but it is much more flexible compare to the nano :D

PERFORMANCE

Do you remember the nano stream making noise during the start up? No need to worry about it with the stream 2. It is super quiet and the Propeller did not side back and forth or do the reverse.

I ran it in the 55g bin for 4hrs and test the temp, the temp stay the same.

[Jar*Head]

Now i really want to sell all my tunze pumps and buy all the stream 2 because of the smaller design, stronger magnet holder :D and i don't have to worry about the holder. The stream 2 has the same feature as the nano stream as for as directional except stronger flow...

[TulsaReefer]

So it made no noise when it started up and didn't have any problems with starting in reverse and having to switch over. I'm assuming you tried it a few times just to see if it was a fluke or was going to be consistent. If so, I think I'm in love...

[Konadog]

You have all the cool toys Steve!

I even have two open ports on my 7095 controller for a pair :D

Did you try to run them on battery power and see if they made any noise?

[TulsaReefer]

The 6085 is a non-controllable version. Still really nice though, would be quite a deal on my Neptune controller where I might want to switch them on and off a couple times an hour to change around my flow. Can't quite tell compared to anything else in the photos but they look pretty small too. Any chance getting a photo next to a well known object such as a soda can, or some other item that will give some perspective.

[Jar*Head]

Lee, i purposely turn it on and off a few time to see if it is going to stall but it still run very quite. I think the shaft make a big different.

Ken, you should try the new stream 2. It is very compact and quiet. I have not try it on the battery yet. Do you think my wife will do the backward flip if see saw me doing something with her car battery? :D. BTW, this is the non controllable pump, i will try to controllable once it become available...

[Konadog]

Yea, I miss read the information on the pump, I thought it was a controllable one. Still a very nice pump.

[TulsaReefer]

Wow, sounds really good then. Maybe the answer to my dreams. I eventually want to buy into the new controllable stream 2's and have them on an aquasurf module for my controller, but until then I need to have a bit more flow than I have now, and a couple of these might fit the need nicely.

[Jar*Head]

Lee, i am using the pump to compare with the sch . 80 union 1.5".

If you are using the 6085 on your neptune system, you can have it on/off every 15 mins

[TulsaReefer]

They are pretty compact. And if I did use them on a the Neptune I probably woudn't turn them off and on any more than 15 minutes, maybe every half hour or more. And might turn a few off at night. Thanks for the photo!

Though with as cool as these look, I'm guessing that there may be quite a few of the old streams on the market soon, for those of us trying to save a little money for now :).

The controllable model is the same size except the outlet a bit larger (Per Roger). I will get couple 6305 and 6205 for my prop system and something to flow along the bottom of my tank :D

Many people already thought about having "Fire Sale" on their old stream. With the new compact design, it will be hard to sell the old :D

[Jar*Head]

BTW, the magnet holder strong enough to hold the pump with 1" thick acrylic...

Steve

What will happen if you turn these off every 2 minutes?

Can you get a picture of them next to nanostreams if you have them?

thanks

Stole this pic from Roger

As for the 2min question, the short of it is you will end up substantially shortening the life of the pump and damage would not be covered under warranty. Due to the nature of the design of a propeller pump it is very hard on the motor and creates alot of wear and tear. All noncontrollable Tunzes are recommended to be ran in at least 15 min intervals or longer

[dbond]

Anyone know where we can get more info on these availability,price,flow etc.

Thanks

[shawnz28]

6305-$834.26

[dbond]

Thanks for the link..
Do you also know if the controllable models will work with my existing 7095 controller or will they only work with the new 7096.

[Jar*Head]

Dbond, the new pump will work with the old controller 7095 and vice versa old pump with new controller.

Shawn, i thought the non controllable is 6135 correct me if im wrong :D

[shawnz28]

Too be honest I am not sure, I have seen both numbers floating around. I copied that from one of Rogers posts. The interzoo flyer says 6125, found earlier posts saying 6135 which is what I posted on our site, which guess I might have done wrong. Thinking there was a model name change maybe to 6125 as output is 12000lph thus the 612x numbering... or maybe was just a typo in the beginning.

[Jar*Head]

ahhhh, got it sir.

[shawnz28]

After getting the few in this week and looking at them, first thing that came to mind was a couple 6105s with 6205 front housings would be nice in my 90g :D

[Jar*Head]

I really like the new design. 6105's in the 90g? You remind me of my friend Michael, i talk him into 2 x 6100 in his 60g :D

I am going to do exactly the same thing, but probably add a nano wavebox too!!!!


so excited. when is the new controller due? October too?

[Jar*Head]

The new controller and the controllable pump will be available in Oct or November

[reefkeeper2]

Are there other methods for securing the pumps other than the magnet holder? My present configuration has tunze pumps mounted on my overflow. Two on wavyseas.

[Jar*Head]

Paul, you can mount it into your wavysea as well. All you need is 1 plastic screw, 1 end cap and a taps set.

[reefkeeper2]

alright!

[Jar*Head]

The 1/4" thump screw work very well :D
