Tunze Nano Streams

I just purchased the 6025 the other day. I have a 65 G and had a bunch of maxi-jets in there this thing not only easy to move but purrs and looks good in your tank(unlike the maxi-jets which are so bulky looking). Worth the 75$ IMO

Mine has started to make lots of noise. Like, noticeable from well across the apartment. I think I'm going to pull it out and clean it, but it seems to me that it shouldn't require a cleaning within a month's operation.

Mine has been up for two weeks and mine is definitely not quiet, but I wouldn't say it's noisy either. I'll post back if mine starts to act up like that...

My first one was very noisy so I took it apart and the impeller shaft was sheared off. It was replaced for me and now the two I have make almost no noise at all. Very quiet.

Yeah, I took mine apart to clean/inspect it, and the impeller/propeller shaft was also sheared off (the metal rod that holds the propeller on was rusted and had broken off). Weird! But it was also replaced for me where I bought it here in Calgary. Gotta love good customer service.

Well, just installed two 6025 nanostreams in the 50g aquarium.

This was the setup BEFORE the Tunze powerheads:
Seio 1500
Fluval 303 (for carbon and surface aggitation)
Deltec MCE 600, which actually has a decent amount of flow for a HOB skimmer.

The two 6025 replaces the Seio and the Fluval 303 canister.

The flow is now slightly greater and definitely more diverse.
It's actually quite amazing - if you place your hand in front of the Nanostreams it doesn't feel as strong as the Seio 1500, but it does just as good a job for flow.

Installation was quite easy, although you have to take some precaution as the plastics are thinner than standard powerheads. Definitely take seriously the warning of placing the two magnets close to each other. If they are within a few inches of each other they will snap together and you'll have a h&ll of a time trying to get them apart. Don't use this product if you have a pacemaker

With 3/8 of an inch of glass between them, it's no problem.

Start-up was almost immediate. If you hear some clanking on start-up, disconnect the power and try connecting again. It shouldn't take more than a couple of tries to get it running in the correct flow direction.

Noise-wise it's a bit louder than the Seio 1500 which is very quiet, even more so for it's size.

IMHO, two 6025 is enough for a 50 gallon aquarium. In conjunction with the Deltec skimmer, total flow and coverage is almost perfect. I have about 65 lbs of live rock.

We will see how this product fairs in the long run.

Cheers.

I've got two 6025s and like them a lot. But one does suffer from the same problem that some Seios have... it doesn't always turn on after being shut off. It can take a half dozen resets before it will run.

I've got 2 Tunze 6100s and a nano 6055. All variable speed, which makes a huge difference in the tank (e.g. they slow down at night and are programmable for storms, surge, waves, etc.).

Expensive, but well worth it. One thing not mentionned on this discussion is the fact that their transformer units are outside of the tank, keeping heat exchange down.

You may want a 7095 multicontroller if you've more than one Tunze pump. I've got one if you're interested (see for sale section).

I've been running my pumps for more than a year without a hitch. They can be noisy when they surge to 100 percent, but it's usually vibration and can be corrected by shifting the pump position.

Cheers,

Erik
