All in one solutions in long term

[Spare time]

So one reason I have held off from switching to something such as all for reef is that I do not do water changes, therefore I am worried that some trace elements that may have little to no use will end up building to a toxic level (ex: chromium, nickel, vanadium, etc.). However, I would love to get an auto doser and have just one jug under my tank that it feeds from (I don't have room for have multiple containers). Also, when I say I do no water changes, that means that I maybe do 20g or so once a year if something goes wrong but I don't have reliable water corrections from a typical water change schedule.

Does my worrying seem valid?

All methods add something that may accumulate. I wouldn’t pick out this method as more prone to that.
