Are these parameters good?

This is my city water and everything looks really low. Am I missing something?

what's the context? You're using tap water for your tank?

Yeah if you are using that for your tank that is really low nutrients for your tank. Plus I am always skeptical of using tap water for a reef tank

I was thinking about it. I use RODI well water now but I think the nutrients in there are wayyyy too low

10% of the houses tested in Raleigh have >50 ppb copper in their tap water. That is much better than many locations, but I still would not risk it without a copper test.

The water also has a lot of silicate. That may be fine, but will be used by diatoms.
