Not science... just a mark on the inside of my tank when I first started it up. The mark was made at my "full" level. Next day I just added water until I reached the line. Repeat that a few days in a row and you pretty much have it figured out. Now it's part of my morning ritual... add 20ml CBalance Part A... add 20ml CBalance Part B... add 6 cups of water... shave... brush teeth...
During the summer, it's around 6 cups. During the winter, it's around 4 cups. (I run a fan across the top in the summer, hence more evaporation.)
But yeah... don't discount the sudden change in salinity. There's a reason we acclimate our fish... right? 4 kool-aid pitchers is a LOT of water. Measure it out and calculate it as a percentage of your tank volume... you might be surprised.
