First time water testing for fish-in cycle


I'm waiting for my cycle to set in my 10 gal freshwater tank. I have four neon tetras in there and some plants too.In the first week, I had I had not fish but only plants and water in the tank and only put in very little fish food once a day. After a week, I put in the fish and today it is three weeks since the day I planted my tank and added water in. Finally I can see a nitrite spike in the water.

Here are my readings from the API liquid master test kit,
Nitrite - 3 ppm
Nitrate - 20 ppm
Ammonia - 0.23 ppm

Are these readings okay? Should I be changing my water? My fish dont seem stressed at all.

First off, I moved this post to start a new thread of its own. It was initially posted in an old thread where few would see it. Should have better luck on its own.

Nitrite at 3 ppm is very high. Ammonia even at .25 is not good for fish. I see you have plants, so before I go further, I'll ask what water conditioner you are using? How often do you do water changes, and how much water each time?

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
