Nitrogen is a vital element essential for metabolic processes, protein synthesis, and the growth of corals and macroalgae in reef aquariums. Studies indicate a tightly regulated nitrogen cycle on reefs, with elevated concentrations in micro-zones near corals compared to the surrounding water (Radecker 2015, Wiedenmann, 2023).

Maintaining balanced nitrogen and phosphorus levels is crucial for promoting optimal growth and vibrant coloration of corals and macroalgae.

Supplementing with inorganic nitrogen offers a precise method to increase nitrogen without introducing excess phosphate or dissolved organics. Typical nitrate tests will reflect all nitrogen forms supplied by this supplement. It is ideally used with an automated dosing system such as the aquavitro sentia dose doser to maintain stable nitrogen concentrations tailored to your aquarium’s specific needs, though manual dosing is also straightforward.

Optimal nitrogen levels generally range from 1 – 2 mg/L (4.4 – 8.9 mg/L nitrate). Pairing this with a complementary phosphorus supplement helps achieve the necessary nutrient balance for reef health.

Directions

Beginner:

Use 1 cap (5 mL) per 160 liters (40 US gallons) twice weekly or as needed to maintain desired nitrate levels. For new or lightly stocked aquariums, start with ¼ to ½ dose and gradually increase as required.

Advanced:

The beginner dose raises nitrogen by approximately 0.78 mg/L or 3.5 mg/L nitrate. To target a specific nitrate increase, apply the formula: 0.009 × volume (L) × desired nitrate increase (mg/L) = product volume (mL). For example, raising nitrogen by 3.5 mg/L in 160 liters requires 5 mL. (Note: 1 US gallon = 3.8 L.)
