The only thing I NORMALLY test for when mixing is my SG. Every now and then I'll test for PO4 just to be anal about it. This is just how I do it, but someone else may have another method. I just make sure my SG and temp is good and SLOWLY pour or pump my fresh mix (heated) to the tank. As long as your SG is where you want it and your temp is good, you should be alright. This is a good place for you to use a sump like we were talking about.
And yes to the fresh water, if you add mixed saltwater for your top-off it'll raise your SG.
Hopefully someone else will chime in and give a second opinion.
