Never add anything you don't/can't test for it's too easy to overdose.

Get alk, calcium and magnesium test kits. If you want to keep corals these are important things to test for and maintain at certain levels.
Alk should be kept between 7dkh - 10dkh
cal between 380-450
and Mg should be over 1250ppm
These and other trace minerals and elements can be kept up with regular water changes but as your coral collection grows your going to find that you have to supplement with calcium, alk and magnesium additives of some sort
