I thought I read you saying to test salinity of your RO/DI water? Making sure this, and pH, temp. are the same as your tank. I know you can't test pH of filtered water. I'm trying to figure out how to deal with temperature b/c my setup is in the garage in Florida. But salinity?

Even if I misread this or it's a typo let me see if I understand this right. The salinity in your tank is a set amount of salt and the only way that goes is through stuff like evaporation. It has nothing to do with the amount of water in your tank. So you only test the salinity of your tank... and if you need more salt you mix it in your filtered water and add that to your tank. Otherwise you don't check salinity or add salt to your filtered water?
