Hanna high range Nitrate vs nyos

[Biff0rz]

Nyos says 25ppm. Hanna says 37.9.

My nitrates have been floating around 25ppm for a while now as I'm battling dinos. But 37.9 seems super high and not close to nyos. Not sure which one I should trust more?

I had pretty much the same result
Nyos was 15ish and Hanna HR 31

Make a 10 ppm nitrate standard.

There is about to be a lot of surprised reefers over the next few months

The error range is 3ppm on the hanna.
