I love knowing what my levels are. And these seem to be spot on

The magnitudinal difference between litmus value and actual chemical titration value can be as much as a 5X magnitude. Not really accurate enough for me to put my Tiger Oscar's existence at risk. However, a person can actually use the litmus tests to confirm a trending pattern, with a certain level of confidence. Beyond that, though, I would not trust the actual coefficients rendered as absolute values.

Seem to be fairly accurate readings because it tests similar to another strip I have that reads 8 items for my pool. I also like the fact that these strips don't expire until 2/2025.

I used these while I was cycling my 75-gallon aquarium. They definitely change color and react to the nitrites and nitrates. I found them easier to read than strips I’ve used in the past. I bought another tube when I ran out

I am an environmental science teacher and I purchased this for a lab my students were performing. It worked well enough for the lab. Wished they had a larger printout.

I’ve tried a couple strips in water that I know has nitrates and the strips don’t change color at all. I purchased the aquacheck brand and they pick up the nitrates fine and change color showing the amount present in the water. These do not change colors at all. Very disappointed!
