Questions:

Had no problems with tap water yet parameters are stable why change ?

No skimmer do i really need one ?

I think i am going to add a yellow tang , are they hardier than most other tangs ? Are they prone to ich too ?

Thank you.

Tank is to small for a tang. Minimum if 4 feet for any tang. As far as tap water goes you usually won't see adverse affects until the tank becomes more established. As time goes on algae becomes more of an issue.
