Hi Frank,

I don't speak German but have been redirected to this thread by my LFS after discussing my issues with my Eheim 2078 and my Profilux equipment. Thanks to google translator it looks like you can provide a firmware update which I can perform myself and that helps with those issues. My current Eheim 2078 has firmware version 4.0. I'm sending a PM with my emial adress. Many thanks in advance.
