What one dose does
PARAMETER
1 g / 100 L
Nitrate
+5.251 ppm NO₃
Calcium
+1.697 ppm
To raise nitrate by 2 ppm NO₃ in 100 L: 0.38 g.
How it’s used
ACS/reagent tetrahydrate. Fertilizer 'calcium nitrate' is usually 5Ca(NO3)2·NH4NO3·10H2O (~15.5% N incl. ~1% ammonium-N) - contains AMMONIUM; avoid or account for it.
Cautions
• Adds Ca (0.32 ppm Ca per ppm NO3) - trivial vs tank Ca but note it.
• Very hygroscopic; weigh quickly.
• Same nitrate-dosing indications as KNO3.
pH effect: neutral.
