keep in mind that water quality can very from house to house depending on what type of piping it has to travel through before it gets to your faucet. They sell RO/DI water at health food stores like Fresh Market and GreenLife. I don't know if you have those in Savannah, but I would recommend that. In Chattanooga, its fairly cheap. Or you could get an RO/DI filter to run your tap water through first. I've been considering getting one of those. I'm no expert, but I think copper is really bad for a reef aquarium. As for chlorine, if you use a declorinator in your tap water, you should be fine. The kind I use is called Prime.
