The old tank crashes are often not a result of neglect but a lack of trace elements that are used up over time and not replaced adequately by water changes alone. Since most of these elements cannot be tested for by the home aquarist since the equipment required is cost prohibited, it is not practical to test and any blind dosing of trace elements risks an overdose. I've seen articles advocating annual 100% water changes to overcome this issue (although I've never made one).
