I started out using Aquaforrest NO3 test when cycling the tank.
After the cycle, I have always had low readings around 0.5-2 ppm
I started dosing a little KNO3 to get it up a bit, feeding more and more fish had no effect.
I recently decided to buy another brand test (Tetra), just for reference. Well, seems Aquaforrest reads around 1-ish ppm no matter how much nitrate is present.
The Tetra seemed to be accurate (tested both with a 15ppm KNO3 solution), but the color scale isn't suited for reef tank values.
I just bought the Nyos test ($40+!!), and still have no clue what to trust.
Nyos reading:
Tankwater shows close to 12ppm, but higher (next point on scale is 25?!)
50/50 Tank water and RODI shows 12 ppm
20/80 Tank water and RODI shows between 5 and 12 ppm
Anyone know a Nitrate test kit that can be trusted (within reason).
Or better yet; give some pointers on how to be able to trust the results?
