I use RO/DI water for my marine tank. Can I use this water also for my freshwater tank and if so do I need to add anything back in?

Yes, if it's purely RO/DI water you'll need to add a percentage of your own hard tapwater. If you're breeding tetras or other Amazon basin softwater fishes, you only need a few ppm total dissolved solids.

They do sell RO mixes, but I think Wetman gave you better advice, add in some portion of your RO water with your normal tapwater to give you water that has some hardness to it...
Once again, welcome to AC...
