Avoid those. Never dose what you don't have a test for...and the tests for those only come into play in very old reefs or unusual circumstances.
Your salt mix [I use Oceanic] contains all those trace elements already. Standard practice of changing out 10 % of your tank volume weekly will replace all those trace elements AND give you a good balance of calcium, magnesium and a good alkalinity, which are the 3 elements to worry about.
I note you're a year old in a 65 reef. Consider dripping kalk, which will free you from dosing even calcium and buffer, make the supplement job about a once a week affair, and all else you have to worry about is your magnesium level [if it's 3x where you want your calcium to ride steady, it will hold both your calcium and alk in balance. With kalk as topoff [just adding pickling lime to your topoff water, basically] and magnesium steady-on, your tank will thrive and corals will grow.
The traces in your salt mix are so very tiny to achieve balance in a 65 that the fineness of the measurements would be SO subject to error it would be scary. Those water changes are your very best way to go.
