Attached is a photo of the result compared to the API test set I usually rely on. The PH of this strip only reaches 6.4 because the color is more yellow than the 6.4 color, so it should be assumed that the PH is higher than 6.4. Nitrate is a bit low but not bad at all. It's handy enough for the occasional water test.
