Spend an extra few bucks and get a bucket from homedepot and mix an addition there, just take a little bit of water from the tank mix it up, then add slowly back in.
Do not add it directly to the tank. Do not add it to the sump if you have a small system.
Some people with large systems can get away with it, but its really not advisable. I sometimes add some to my overflow where most of the salt sinks to the bottom of the chamber where it slowly mixes with water from the tank and leaving the overflow chamber. The saltyer water stays at the bottom because it is more dense (and makes a neat heliocline). BUT the only reason I actually do it at all is because my sump is not only 14 feet away from the overflow (giving 14 feet of mixing time, but my sump is really three chambers in two separate tanks. The first chamber is where the skimmer is and almost all the overflow water goes through the skimmer. The second chamber is an skimmer effluent chamber/'fuge, the third chamber, actually a 180 gallon tank is last. So the salt has lots and lots of time to dissolve before hitting anything alive. That all said, I still only do it like a cup at a time and at that I rarely do it.
It is much easier and safer to mix up the salt in a separate container with RODI water and then add that slowly to a high flow area of the sump or the overflow.
