Help me understand this Salifert Nitrate Test

Can it really be Zero if sideview is indicating closer to 10? (100/10)

Yes you are at 10 ppm, not sure where you see 0

To me from the top that appears to be about 5 and from the side about 50. Using the divide by 10 rule, it’d still line up to about 5

Thats one of the issues with these test. Follow directions if it says look top down ( in your case) do so. that is the closest version of the truth.

The tests gives you the possibility to use both top and side (side with /10 rude)

Thanks - yeah I was expecting 5-10 as well

Zero is second pic - lined against 0 colour, it just seems to match. Slight difference as you move up but side view is def telling me it’s higher than zero

5-10 for me too.

Just in general, Salifert is really easy and consistent at showing 3 levels. First, nothing, Second, some (where you are). Third, a lot.

This is good enough for most people. If you want an exact number, then Hannah is your tool, but it is a real pain to use.

Second pic shows 10.

Zero should be clear looking down. Mine is usually very pale pink....from the side with conversion...2.5.
