No and no.
It's all the same stuff when it comes to FW vs. SW, but....it's not all the same stuff when it comes to carbon vs. carbon. Some carbons apparently have phosphates in it, whereas others claim to be phosphate free. I use Black Diamond by Marineland for both FW and SW. It's one of the "phosphate free" carbons.

HTH,
