Water Paremiter Help!

[Gunreaper]

Hello all, I recently set my tank up about a month ago. I have a 200 gallon Freshwater tank with a couple gouramies and some danios. I checked the water with the 5 test in 1 strip.

Below is the parameters according to the Jungle test strips

Nitrate: 20
Nitrite: 3.0 ppm
Hardness: 150 ppm
Alkalinity: 180 ppm
PH: 7.8

I just did a 20% water change and still pretty close to the same readings. I know my Nitrate and Nitrites are a high. All fish are still ok. Any idea's?

Them test strip cards are not that accurate, liquid test kits are the best.
The nitrate reading not high its fine, its the nitrite and ammonia reading that we need to know more in cycling tank.
Water changes and increase aeration in the tank.
Salt helps in a cycling tank.
It's a teaspoon to 5 gal, but best of adding it gradually.
