It's somewhat rare for freshwater fishkeepers to have an RO/DI unit and those who do are using the RO water for their tanks. I think you might want to ask this question in the saltwater section. Personally, I have no idea what sorts of stuff might be in the waste water so I'm not so sure it'd be a good idea to use this stuff in any fish tank.

Agree. One uses RO to remove substances that otherwise make the water unsuitable or less suitable for the fish; why would one then put it back?

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
