Don't use tap water in your tank.

It's not unusual to get a reading for ammonia in tap water. That's because some municipal water systems disinfect with chlorine and chloramine.... The chloramine is a compound of chlorine and ammonium, which does not evaporate in long supply lines.
Ammonium is not as reactive or harmful as ammonia, but it often gives a positive reading on tests. Some test kits in fact state they measure both compounds. If the aquarium has a working nitrogen cycle, an aquarium water test should indicate close to zero ammonia.

Looks good. Your Nitrate should still be around 30ppm till you do a water change though.

Big Big no no!!! Do you drink tap water? Get a reverse osmosis system online, they are cheap and you won't ever need bottled water again. You won't have a successful reef tank with tap water. Even filtered water is going to have too much junk in it.I thought a lot of people do it?

FWIW, there are lots of reasons to not use tap water: ammonia, copper, lead, chloramine, silicate, phosphate, nitrate, etc.

Are you cycling a new tank or something? You should not have 2 of those in the tank water. "If the nitrate number stop rising then your tank is ready" from BRS 
Tested this morning and this is what I got, how am I looking?
