What if I boil the city water?You need an RODI unit. You can get them almost anywhere like amazon, marine depot, ebay ect. You can purchase the RODI water at your local LFS or get the saltwater already made from them too. It's cheaper and less of a pain to just make your own at home. So you need the reef salt of course and a machine like this one...

). Depending on where you live, my city is only about 35 ppm out of the tap, but I've heard others on the forum with tap close to 300-500 ppm out of the tap, which really is not suitable to a marine tank, especially if you have inverts.
