If your dKH falls within standard parameters after you add salt and mix for 24+ hours preferably with a ph then it's not necessary.

I have to buffer mine very slightly (half a teaspoon to 15 gal) sometime using ro/di because my alk ranges between 6-8 dKH with the salt I use and I like it closer to 10. I only use SeaChem Marine Buffer to increase it and I add buffer about once every 2-3 water changes.
