I tested my tap water and although it doesn't look like Nitrites are present, it is testing positive for Ammonia and I think Nitrates as well. I've put the results below.
Image 1: Ammonia
Image 2: Nitrites
Image 3: Nitrates
So I retested just to be sure and these were the results. Seems like the pH test didn't work the first time. But the High Range pH stayed the same colour.
I am visually impaired so I may be reading it wrong as it can be quite difficult for me to distinguish between the colour shades.
