Seachem Reef Nitrogen is a concentrated inorganic nitrogen supplement formulated specifically to support the growth and coloration of corals and macroalgae in marine and reef aquariums.
Product Overview
Seachem Reef Nitrogen is a targeted supplement providing 25,000 mg/L nitrogen and 110,750 mg/L nitrate in a fully testable form without adding unwanted phosphates or dissolved organics.
Ideal Levels: Generally ranges from 1 to 2 mg/L nitrogen (approximately 4.4 to 8.9 mg/L nitrate), varying based on system demand.
Available Sizes: Offered in 100 mL, 250 mL
Beginner Dose: Use 1 cap (5 mL) per 160 liters (40 US gallons) twice a week, or as needed to maintain target nitrate levels. For new or low-bioload tanks, start with a 1/4 to 1/2 dose.
Advanced Calculation: The beginner dose raises nitrogen by 0.78 mg/L (around 3.5 mg/L nitrate). Target adjustments use the formula: 0.009 multiplied by tank volume in liters multiplied by desired nitrate increase in mg/L equals the volume of product to add in mL.
Best Practices: Use alongside Seachem Reef Phosphorus to maintain a balanced nitrogen-to-phosphorus ratio for optimal coral health.
