My first bag of salt is nearly done (Seachem Marine), and I'm thinking of using Seachem REEF salt from now on, which apparently contains more trace elements for corals etc. (as I now have corals in my tank).

I do a 25-30% PWC every 2 weeks. Am I ok just doing the full changeover PWC with all of the new salt? With it being the same brand, I guess it's not really much of a problem?
It should not be a problem. If you are worried, try doing 10% water changes with the new salt once a week for a few weeks before going back to your bi-weekly schedule. I am waiting for my LFS to get in the new Seachem Reef salt to give it a try.
I agree, try a few smaller PWCs. I didn't have a problem switching from IO to RC, but I have heard a few folks having their tanks crash, when they tried too much at a time.
