Look It Up
Wow, I'd definitely do tests on your tap water to see exactly what the readings for each are. If nitrates are that high from the tap you may need to cut it with RO water or something, or get a lot of live plants. Just remember if you start using all RO/RODI water you're going to need to reconstitute it with minerals like RO Rite or Seachem Replenish.
I hope your fish gets better.
