Tap water! Bad idea????

[Buddyboy]

Hi All,

Just wanted to know your opinion on using tap water for an initial tank fillup?
I have a rinky dinky little Aqua Pharm Tap Water conditioner and i'm not looking forward to having to make 38G of RO water with it. Seems like it would take quite a while. Would using tap water to start out my tank be a bad idea? Would successive water changes with RO water clean up (dilute) any chlorine, phosphates, etc. in the tap water? I plan on having a few hardy corals, a few fish, cleaner shrimp, etc. Also, does anyone here use tap water in their reefs? Thanks for your help!
