My personal 2 cent opinion . I've been using all sorts of trace dosing ...... ( other than regular KH, CA, MG ). I've stopped using all those for past 3 months especially carbon dosing , all my sps colored and no issues .
But the hind side , I conduct regular water change once a week ( 20 % ) to keep No3 and Po4 in check , and of course control feeding.
Somehow I personally feel if you have a good salt mix , I don't have to dose the others traces
Pls don't "bomb " me , this experiment is only applicable to my tank
