I know my water is pretty crumby. I live in the city and although I have never tested it for different minerals and chemical content, I know it's high in copper and probably a bunch of other stuff that's pretty nasty for a reef. This will be my first saltwater aquarium and I want to get an RO
system. My question is, how many gallons per day am I looking for here? The aquarium I will be setting up is a 90gal.
I looked briefly for other topics about it here, but didn't find what I wanted. Maybe I didn't look in the right spot.
Any help is much appreciated.
