I remember you explaining that before what I basically did is use the water from the fish store as a control and tested that water with the water in the tank that I had cycled and ready for quarantine.And everyone's screen will show a slightly different colour for your photos depending on how the device is set up
There are two types of result, zero and not zero. Not zero needs attention while zero is fine.
With the nitrite tester, if it is blue, that's zero. Anything with a purple tinge is above zero.
Ammonia is a bit trickier. Yellow is zero, anything with a green tint is above zero. But a lot of people never see the yellow of zero even with a tank that has been running trouble free for years. The colour of the tube is influenced by the type of lighting, and different eyes apparently see the colour slightly differently.
If your testers clearly show blue and yellow, you don't need to do a water change. But if there is a hint of purple and/or a hint of green, do the water change.
