The carbon filter plumbed in before your RO membrane takes care of chlorine. Without it, your costly RO membrane wouldn't last very long. So yes, all the chlorine should be gone in your waste water, no need to treat with Prime.
Last question, do you still need to add suppliments with the waste water?
If so what suppliments do you add as of course i dont dose my fw planted tank with anything but flouriish excel?
