Does RO remove chlorine out of city water?
Mine has a chlorine filter. with total of 3 filters on it
@bryan @Guitfidl
Ro filtration will remove most minerials and most have a charcoal filter to remove chlorine and fluoride
So the answer to the question is yes it will
Good choice in filtration 
Water will be pure almost like a distilled water once filtered

Good. I’m wanting to add great white microbes and I didn’t want the chlorine to kill them. After I start should I ad cal mag?

What are you using for nutes
Since you’ll be removing all trace minerals the only thing that will be in the water is what you put in it @Guitfidl
