Nitrate test colour, is this 10 or 20??

[Levinson]

Greetings everyone.
So I did a nitrate test today with an Api test kit. I know they suck but that's what I'm stuck with. I've done some tests with it before but was always a little unsure about the colour I'm getting and wanted to seek some professional advice from the experts.
What do you think is the colour I'm getting (photos below)? I'm guessing it would either be 20 or 10ppm. The light also seems to play a role in how they look too. Is it just me or does anyone else also find these test colours hard to read every time?

It definitely looks like 10 to me. API tests can be difficult to read.

Depends. If your feeling optimistic and you generally feel good, it’s a 10. If your feeling miserable and stuff isn’t going your way, it’s a 20.

I’d call it 15

Looks like 5 to me.

I’d call it 15, do a water change, toss the API kit in the trash, and order a Nyos test kit. But that’s me

Here's my take on APIs nitrate kit: yellow good, orange ok, red bad. And I'm not knocking it, I use them but not for fine resolution. I simply know I have work to do if it's not yellow and I do not believe yellow is necessarily zero, just below 5.

I'd definitely lean towards that being 10ppm

Looks like 20 to me so call it 15.

Get a salifert

I would call that 8
I don't see any red

 

[Levinson]

Wow, thank you all for your input. Looks like I'm getting some different answers. I'll go with 15> for the time being.
