Seachem Reef Nitrogen™ is a concentrated (15,000 mg/L) blend of nitrogen sources specifically formulated for the modern reef aquarium. In ultra-low nutrient systems (ULNS) with aggressive protein skimming or carbon dosing, nitrates can often drop to undetectable levels, leading to coral starvation and tissue loss. Reef Nitrogen™ provides a chemically pure source of nitrogen to maintain the biological balance required for lush coral growth and vibrant pigmentation.
Reef Nitrogen™ is engineered to provide a safe, inorganic source of nitrogen to fuel the metabolic processes of corals and beneficial bacteria.
Dual Nitrogen Sources: Utilizes a proprietary blend of both nitrate and ammonium-derived nitrogen to provide an immediate and sustained nutrient source for corals.
Prevents Nutrient Limitation: Essential for preventing "Pale Coral Syndrome" and stunted growth caused by a total lack of nitrogen in the water column.
Supports Zooxanthellae Health: Provides the necessary fuel for the symbiotic algae within coral tissues, resulting in deeper, more natural coloration.
Fuels Biological Filtration: Helps maintain the bacterial populations required for effective phosphate reduction and carbon dosing systems.
Precise Dosing Control: The liquid formula allows for micro-adjustments, ensuring you can reach your target nitrate levels without overshooting.
Why would I want to add nitrogen to my reef? In very "clean" tanks, corals can stop growing or begin to bleach if nitrates drop to absolute zero. A small, controlled amount of nitrogen is necessary for the production of amino acids and proteins within the coral.
How much Seachem Reef Nitrogen™ should I dose? The standard dose is 1 mL per 160 L (40 US gallons) to raise nitrate levels by approximately 0.1 mg/L. Always test your nitrate levels before and after dosing to ensure you stay within your target range.
What is the ideal nitrate level for a reef? Most successful reef hobbyists aim for a stable nitrate level between 1 and 5 mg/L. Levels consistently above 10 mg/L may begin to fuel nuisance algae growth.
Seachem Reef Phosphorus™: The essential partner to balance your "Redfield Ratio" by adding phosphate alongside nitrogen.
Seachem Reef Plus™: Provides the amino acids and vitamins that corals need to fully utilize the added nitrogen for tissue growth.
Seachem de*nitrate: Keep this on hand as a biological safety measure to help naturally process nitrogen if levels rise too high.
