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...
