Have you ever gone on vacation and had problems with the tank
sitter not adding makeup water? One time, a couple of years ago, when I
got back from vacation, the tank's water level was 2 inches lower than I
ever let it get. I made the mistake of replacing all the water at once.
By doing this I changed the salinity of the tank very rapidly and lost every
starfish in the tank. Luckily that is all that I lost.
This is a calculator GARF created that will estimate salinity
changes due to evaporation and/or the addition of fresh water to makeup
