I'm not a proponent of non-water-change views at all, but aren't those trace elements easily replenished with today's commonly available additives?
I do agree though, that not all trace elements necessary to propagate the life of many organisms are not fully understood.
I still can't think of NOT doing water changes... Borders on animal cruelty in my mind still...
