Utterly frustrated with Tunze streams..

Just measured the output from the Jebao controller, it's 5v max.

Now the weird part. With the Profilux set to 0-10v I get 4.89v at the control circuit out to the pump. There must be a resistor in the adapter for the Profilux circuit.

Temped to just hook them up to an old wave maker power bar.

Weird. I have all my original tunzes still working. I've only had one motor block and one driver box die out of the lot and they were a questionable setup when I bought them (modified or something). My wavebox is going on 8 years old.

Course now that I've said that they'll all die slowly over the next few months...

BTW, when you order RW-20s to replace your Tunzes you can order one of these to control them with an Apex.

I just ordered 2 of these from reef supplies for same price.

My original units, 6100 model, lasted about 8 years. But replacement parts didn't last, newer pumps didn't last, and the replacement cost was just too high to buy all new pumps. Even if Jebao die after a couple years, still the same cost over a 8 year period, without the initial outlay of cash.

Yeah its unlikely that I'll stick with the tunze once these ones start to pack it in. I'll be switching to the most economical flavor-of-the-month ones.

I emailed Tunze to ask why the titanium shaft in my 6105 corroded through. He said some of them accidentally got stainless shafts, but apparently they can be repaired. Still waiting to hear back from the Canadian distributor.

This is after the first two were replaced under warranty because the shafts came loose.

They say "made in Germany" but I'm not sure I believe it. My experience with German products is that they last forever.

BTW, I rebooted my Profilux last night, and the RW-15s have been running fine since.

It's unfortunate that some of you are experiencing, or have experienced, issues with your Tunze streams. I use them exclusively in my tank and everything about them has been nothing short of amazing. At this point I wouldn't consider anything else.

Oh, agreed, great pumps. My first pair cost me $1000 and lasted 8 years. I just can't spend another grand to replace them, especially after seeing some of the smaller units fail under 2 year mark. The original WP series Jebao appear to be short lived, but the RW I have now just keep going.
I also can't replace the 6100 series Tunze, and I don't like the design as much of the newer units. So, for under $200, I got comparable flow and control.
