what should i test for in my water

hey guys i just want to get some input on what you or most reefers test for in there water. I already understand testing your salinity is very important for success along with ammonia, nitrite, nitrate, and pH. I will be starting to stock my nano tank soon with just a few fish but mostly corals. Of course I'm a noob at this all but am trying to give it my best shot. Besides what i have already listed what else should i test for in my water to ensure my coral and fish are healthy and increase their growth.
