Nitrogen Supplement for the Reef Aquarium

Delivers Nitrogen in a fully measurable form

Concentrated 25,000 mg/L Nitrogen (110,750 mg/L Nitrate)

Nitrogen is a vital element necessary for metabolic functions, protein formation, and the development of corals and macroalgae. Studies indicate a tightly regulated nitrogen cycle in reef environments where concentrations are elevated in micro-zones adjacent to the corals (Radecker 2015, Wiedenmann, 2023) compared to the surrounding waters.

It is crucial to maintain nitrogen levels in conjunction with phosphorus levels to promote optimal growth and vibrant coloration of corals and macroalgae. Supplementing with inorganic nitrogen offers a precise method for boosting nitrogen without introducing phosphate or dissolved organics. A standard nitrate test will detect all nitrogen forms provided by Reef Nitrogen™. Reef Nitrogen™ is perfectly compatible with an aquavitro® sentia™ dose doser for maintaining nitrogen at a steady concentration tailored to your aquarium's specific needs. Additionally, Reef Nitrogen™ can be dosed manually with ease. Ideal nitrogen levels can vary but typically fall within the range of 1 – 2 mg/L (4.4 – 8.9 mg/L nitrate). Utilize Seachem’s Reef Phosphorus™ to establish a harmonious balance between nitrogen and phosphorus levels for the best outcomes.

Style, Comfort
Size: 9, Color: Sand
If I could give a Ten Star review, I would. Hands down the most comfortable pair of sandals I have ever owned. I wore them 16 days straight while touring Italy. Comfortable and goes with all of your outfits. They pack well in a suitcase too. Light weight.

Wonderful
Super comfy and easy on and off, yet stylish imo! I could walk miles in these as a 56 yo and have worn them for three years! I hope they never stop making them. The only tweek I would suggest is to cover the footbed with leather or suede not cloth so they would last longer!
