Water Chemistry Levels

Greetings and hallucinations!

I started a 29-gallon aquarium a month ago with a few zebra danios and a
couple of black tetras. I've been doing the water chemistry levels
religiously as it is going through the nitrogen cycle but the readings
I'm getting are alarming from what the chart says they should be.

There was a handy chart included with the aquarium. Normal levels as
per the sheet are in brackets for the fourth week of the cycle (20%
water change complied with last week).

Ammonia: 4.0 mg/L (normal 0)
Nitrite: 5.0 mg/L (normal 0 - 0.5)
Nitrate: 20 mg/L (normal 20)

Shouldn't the ammonia and nitrites be decreasing if the nitrate level is
at it's norm? The fish seem ok but the water is cloudy.

Forgive me, I'm new at this... Can anyone offer advice?
