Hey buddy these I've had for a few years some have expired but I just use the Elos up since I already have it. I obviously check after with a new box of salifert... certain test kits are ok to use if they haven't been expired too long for instance when I check my Hanna alk which is expired against the salifert they are only off by .03/4. But for Hanna I would advice if you have expired or close to expired po4 tests to not use because they're off by quite abit.
Your original question about salt I like aquaforest reef salt
