It is finally time to fill up my 120g system! I have a couple questions about the RO/DI water though. The water coming into the system is about 130 tds and the water out is hovering about 6-8 tds. I am using city water through the unit. Are these numbers ok, and do i still have to worry about chlorine? What are the needed treatments for the new water? My set-up is going to a fish only system with maybe a few soft corals/polyps. thanks.
