Color Blind…Need Your HELP

WOW, here I'm trying to get mine to drop...it's hitting around 200+ So high it's hard on both the plants and fish.

That’s the same as my test on the IBCs but that’s after adding 100ltrs of aquarium water each week where the nitrates are 100/160ppm. Here is a resent clip I found on how to do the test. I find her clips quite funny actually.

She stuffs up on a few of her test.
But I found I was doing the test wrong before I found the clip?
