This is exactly what I'm setting up the tank with. A 4g nano.
To me it just seems easier to use a single water source (ro/di) which I know will have the exact same parameters every time and then add the same amount of buffer or whatever every time, vs trying to mix water from two different sources and then adding more stuff to add or counteract.
Then again, I'm the newb here so what appears one way in my head, may end up being completely different in practice.
