It is probably more important to figure out what the right amount is for your containers and then just be consistant with it. I rarely check the change tank because I know how much should be in there per the qty of water. I check the main tank afterwards to make sure nothing got screwed up, but so far it has been working great.

OK, probably a really stupid question, but aren't most refractometers supposed to take the water temperature into consideration? If so wouldn't that mean that you would just mix to whatever salinity you are wanting rather than trying to mix to a different salinity based upon the water temperature?
