Not many want to hear this, but there are decade-reliable products for every necessary piece of tank equipment, except for heaters, which only seem to last me 3-5 years. All of these can be used in redundancy so that failure does not mean death. Most of these are not even very expensive and most have good warranties. It is the people who screw this up most of the time. Other than the tank exploding, I have no equipment that that could fail that would cause a crash unless it was not noticed for days and days.
Not many want to hear this either, but auto dosing is not even close to being foolproof and reliable - many crashes have been reported for many years.
