I think this depends a lot on how crummy the water is to begin with and what kind of shape the RO unit and its membrane are in and how the waste control is set. A bad enough RO will simply put out what it gets in, and if your fish can live in that they are fine. I would bet that many apistos and neons could live in six nines water.
