It's easy enough to test your tap water for phosphate. Then you'll know for sure if it'll be a problem or not :-)
Yes the other junk that is dissolved in tap water will end up in your tank. Whether or not that's actually a bad thing, I don't know :-). There are lots of people who use tap water for their reefs with success.
You're welcome
