Can tank water be ROed?

[Que]

Is there a way to RO tank water and if there is would you want to?

Q

interesting thought. it would be great if you could create a closed system that RO'd waste water and reintroduced it. water's not free.

Its possible, with an RO filter pump, but I'm sure the RO prefilters would constantly get clogged from fish waste.
