I use RO/DI water for top offs. Since I also have a reef system, I need the RO/DI unit anyway, so using it to top off the planted system is an easy choice.
To store RO/DI I have found the best all around container is a round Rubbermaid Brute Trash can. Just to be sure there will be no problems, season them first by filling them up with RO/DI water, then add a few handfuls of cheep "aquarium salt" (Rock salt). Add a powerhead and circulate for a day or two. Then rinse and repeat. Do this until there is no "plastic smell" coming from them.
