What one dose does
PARAMETER
1 ml / 100 L
Nitrate
+1.12 ppm NO₃
Ammonia
+0.0243 ppm NH₃/NH₄⁺
To raise nitrate by 2 ppm NO₃ in 100 L: 1.8 ml.
How it’s used
Beginner: 5 ml per 160 L (40 US gal) twice a week; new or lightly stocked tanks start at 1/4-1/2 dose. Typical target 4.4-8.9 mg/L nitrate. Formula: ml = 0.009 x liters x nitrate rise.
Cautions
• Contains a small ammonium fraction.
• Raise slowly; balance with phosphate.
Sources
Calcium, magnesium and ammonium nitrates (25,000 mg/L N). Seachem's 3.5 mg/L nitrate counts all N as nitrate; strictly the nitrate-N part is ~3.2 mg/L NO3.
