just get a 5pack from fauna. honestly not that expensive. especially if you have corals worth a few hundred alraedy. just do 2 like 1 month apart and you will know how much to dose.
but yea. goni like maganese. dose some trace. usually your other elements are low like chromium, cobalt, boron, flouride.
