I just started topping off because i had to get rid of my glass top. How do other people top off. I am afraid of killing corals because of the mixing water in the tank. If you dont have a sump where would you top off in the tank?
As long as you top off frequently, it shouldn't be too big of a concern. Do it away from corals and and fish. As a general rule, the more a solute is like a solvent, the quicker it dissolves. Since fresh water is very similar to salt water, it dissolves very quickly.
