you can use softened water for ro (and it will extend the life of your membrane). but i think his question was about the waste from the softener which will contain salt and mess up your ro if you try to run it through it. I am sure you could run the waste water line out to the garden or a barrel outside to use for something outside but it is not a good candidate for any aquarium related use.
