Hello,

It depends how quickly and by how much you want to raise your salinity. I usually just wait for the tank water to evaporate over a couple of days. When the tank water evaporates, the salinity increases.

If you want to increase the salinity by greater amounts and in a short amount of time, then just do a water change. The fresh salt water can have slightly higher salinity...but not too much (say no more than 1.030). If it is too high, than the calcium and magnesium in the fresh saltwater may precipitate out.

Hope that helps.
