I have a friend who runs a local oil change/car wash buisness. They have a huge RO water filtration system. The thing holds over 1000gal of water in a tank. They use this water for there spot free rinse system. My question is would it be ok for my aquarium. He said I could have as much as I wanted for free. It looks the same as most RO systems except this one is about 5 feet tall. I would get the water straight out of the filter system, and not from the car wash bays or anything.
