Yes anything mechanical or electrical can fail, and Tunze has both. Lots of people on this forum and many others that don't use Tunze and have never had problems either. Tunze makes a good product but so do many other companies which also have a second level failsafe. Tunze pumps constantly dieing seems to be very common on any forum you go to and it's kind of hard for an ATO unit to keep your reef stable and safe when it's not working. Tunze would be a much better product if you could add your own reliable pump instead.
