Hi all! I recently bought these together to use on my current setup with the DDR going to my Calc and Alk and the DOS to be used as an automatic water change unit since I already have another DOS. However, I have decided that I prefer to manage my own water changes and I don't like the fit of the DDR in my stand. Both are fully operational, tested but not used by me. They came from another reefer who was breaking down his tank and getting out of the hobby. Comes with all required cables and boxes.
