Nyos vs. Hana nitrate testers

[DmitryB]

Did readings on my IM 40 tank for the first time since setting it up a few days ago.

Having trouble setting up my N-Fill ATO because I can't get the placement of the sensors right. Salinity is at 1.024. There's no livestock in the tank - can I just add a little bit of salt in there and let it mix until I'm at 1.025??

Now the readings, showing Nyos vs. Hana on Nitrate.

Salinity: 1.024 (Milwaukee digital)
pH: 8.2 (RedSea)
kH - 10.1 (Hana)
Nitrite: 0 (Hana and RedSea)
Ammonia: 0 (RedSea)
Nitrate: 30 (Nyos) and 15.2 (Hana)

What's up with the difference between Nyos and Hana Nitrate testers? Does it matter?

Wouldn’t matter much to me since both are within my target range.

No idea which, if either, is more accurate.

I would be more interested in trends rather than the deltas between the two checkers, stick to one of them as they bother work and lessen the complication especially at the early stage of setting up a tank.
