What one dose does
PARAMETER
1 ml / 100 L
Nitrate
+0.3067 ppm NO₃
To raise nitrate by 2 ppm NO₃ in 100 L: 6.5 ml.
How it’s used
50 g/L x 0.6133 = 30.66 g/L NO3; 1 ml in 100 L = 0.307 ppm NO3 (0.0693 ppm N).
Cautions
• Only dose nitrate to correct NO3 that is bottomed out (e.g., <1-2 ppm with algae/cyano/dinos or a carbon-dosing stall); typical reef target 2-10 ppm.
• Adds K (0.63 ppm K per ppm NO3) - helpful if K is low, account for it if K is high.
• Oxidizer: keep away from organics/heat; regulated purchase in some places.
