I'm having some trouble getting a straight story or any reliable information from the internet about whether or not to use RO/DI water for topping off my freshwater tank. I understand that tap water is better suited for initial set up and water changes so I am specifically referring to topping off due to evaporation. It would seem to make sense that using use tap water for evaporated top off would eventually increase the concentration of "stuff" contained in the tap water and that RO/DI would keep those concentrations consistent. However, this doesn't seem to be normal practice. Any thoughts on this from the experts out there?
