Seachem Reef Nitrogen

Seachem Reef Nitrogen is a nitrogen supplement for reef aquariums that provides nitrogen in a fully testable form to support the metabolic processes, protein synthesis, and growth of corals and macroalgae.

  • Nitrogen Supplement for the Reef Aquarium
  • Provides Nitrogen in a fully testable form
  • Concentrated 25,000 mg/L Nitrogen (110,750 mg/L Nitrate)

Nitrogen is an essential element required in metabolic processes, protein synthesis, and growth of corals and macroalgae. Research suggests a tightly closed nitrogen cycle on reefs where concentrations are higher in micro-zones near the corals (Radecker 2015, Wiedenmann, 2023) than in the surrounding water. 

It is important to maintain nitrogen levels along with phosphorus levels in order to allow for optimal growth and coloration of corals and macroalgae.

Supplementing with inorganic nitrogen provides a targeted means of increasing nitrogen without also adding phosphate or dissolved organics. A typical nitrate test will show all forms of nitrogen being added by Reef Nitrogen™. Reef Nitrogen™ is ideally suited for use with an aquavitro® sentia™ dose doser to maintain nitrogen at consistent concentration based on your aquarium's unique demand. Reef Nitrogen™ is easily dosed manually as well. Ideal nitrogen levels will vary but generally range from 1 – 2 mg/L (4.4 – 8.9 mg/L nitrate). Use Seachem’s Reef Phosphorus™ to achieve a balance of nitrogen to phosphorus levels for optimal results.

Directions:
Beginner
Use 1 cap (5 mL) per 160 liters (40 US gallons) twice a week or as needed to maintain desired nitrate levels. For new aquariums or aquariums with low populations of coral use ¼ to ½ dose initially and gradually increase as necessary.

Advanced
The beginner dose raises nitrogen by 0.78 mg/L or approximately 3.5 mg/L nitrate. To target a specific nitrate level, increase dose according to the following formula: 0.009vn=m where v= volume of tank in liters, n=desired nitrate increase, and m= volume of product to use in mL. For example, to raise 160 liters by 3.5 mg/L nitrate you would use 0.009*160*3.5 resulting in 5 mL to dose. For reference: 1 US gallon=3.8 L.

Wonderful product

I used this on a bald spot I had and it worked extremely well. Consistency is key though it needs to be used every day

It works and I love it!
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
I love this product.. been using it for a few months now. My hair is more manageable and my thinning crown looks and feels fuller. The smoky smell, am not bothered because it disappears after a few minutes. I use it twice a week, massage very little amount on scalp and hair, then the next day wash it off with shampoo. I used to need to dye my gray every 3 to 4 months when some appear. Now, it's been 4 months since my last visit to the salon. I noticed my hair has darken a bit. I can delay my salon visit for another month unless I need a haircut!! Yehey!

Good moisturizer. Rich scent.
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
Raw Batana Oil provides goods moisturizing to hair and scalp and best applied with a little heat or steam. Pomade goes on easily once heated and does not feel heavy, greasy, or oily. Its rich fragrance eases on the nose after a short while. Difficult to say whether it is actually useful or whether it encourages hair growth. Leaves hair soft and easy to style.

Batana Oil
I bought a set of batana oil set. This batana oil hair growth kit is a practical option for nourishing the scalp and improving hair condition. It includes both a liquid oil with a dropper for easy application and a thicker raw oil for deeper conditioning. The texture is rich yet manageable, helping to hydrate dry hair, reduce frizz, and add softness and shine with regular use. The natural, slightly earthy scent may not suit everyone but fades over time. While noticeable hair growth requires consistent use, the kit performs well for moisture, scalp care, and overall hair strength.

Love it
The real deal. As soon as I opened it, smells like coffee. Not greasy at all. Nice size and the bottle with oil is larger than I thought. Had to get another. Will sell out. Love the way it fills in my hair.
