Let me rephrase this so it makes more sense.

You are making an assumption also. You are assuming that you are not
accumulating any of the elements you are adding (from your saltmix)
into your aquarium (those not removed with a water change), which
would result in an overdose.

What mistery elements are you thinking of ?
And what process would allow accumulation
of an element during periodic water changes ?
