Need help to know what nitrates are?

[Franco1024]

Need help with Red Sea nitrates results. I’m am leaning towards 20 but it can see some 50 In it. Any thoughts? All pictures from same results

20 ppm would be my call.

 

[Jekyl]

Agreed. Maybe 30

 

[Pistondog]

Above 20, less than 50 ppm is what those results say.

 

[Franco1024]

Thank you all I just did a water change before the test I’ll retest tonight

20. Look under a 6500k light.

The only way to measure the nitrate concentration when they reach this level is to dilute the sample with freshly prepared saltwater.

Dilute the sample to the 0-10 ppm range. In your situation, I would try a dilution of 1 mL aquarium water diluted to 10 mL with new saltwater. You could use RO/DI for dilution. The reading will be a bit high.
