When I recently got my 6055's hooked up to my controller, which has worked flawlessly for two years with the 6000 Tunze Streams, it started doing being weird on the feed mode. When I hit the red feed button one nanostream shuts off and does the "safe fish" spit every 20 seconds, the other one just runs full bore. I checked the controller and it appears "channel 1" where it is hooked into does not power down, there is a green light above the channel name while the other 3 "port lights" are dark. Any idea why "Channel 1" wont shut down while I feed?? It never did that when I had the streams attached.
