If doing water changes in a marine aquarium do you need to add any type of buffer or extra minerals to the water at each water change? If so what are some of the products that would be recommended? Thanx for any help/suggestions.

That really depends on what type of tank it is and what the levels of the newly mixed SW are. As a general rule, no you do not need to add any buffers to your newly mixed water. For my reef though, I have to add calcium chloride to get the CA level up and bring the alk down. That is all I would be concerned with, if I were you, there are plenty of traces in the new water, just test it for CA and ALK, buffer if necessary. If you have a FO or FOWLR, it probably isn't necessary to buffer or even test.
