Seachem Reef Pack NPK

The Reef Pack™ NPK takes reef supplementation to the next level. In many reef aquariums, supplementation with nitrogen, phosphorus, and potassium can enhance coral and macroalgae growth and color.

Reef Nitrogen 

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.

Reef Phosphorus

Phosphorus is an essential element required in metabolic processes, protein synthesis, and growth of corals and macroalgae. It is important to maintain phosphorus levels along with nitrogen levels in order to allow for optimal growth and coloration of corals and macroalgae.

Supplementing with Reef Phosphorus™ provides a targeted means of increasing phosphorus concentrations effectively without also adding dissolved organics.

Supplementing with Reef Phosphorus™ provides a targeted means of increasing phosphorus concentrations effectively without also adding dissolved organics. Reef Phosphorus is ideally suited for use with an aquavitro® sentia™ dose doser to maintain phosphorus at consistent concentration based on your aquarium's unique demand. Reef Phosphorus™ is easily dosed manually as well. Ideal phosphorus levels will vary but generally range from 0.02 - 0.05 mg/L phosphate. Reef Phosphorus™ contains 0.117% elemental phosphorus. Use Seachem’s Reef Nitrogen™ to achieve a balance of nitrogen and phosphorus levels for optimal results.

Directions - 

Beginner

Use 1/2 cap (2.5 mL) per 160 L (40 US gallons) once a week or as needed to maintain desired phosphorus levels.

Advanced

The beginner dose raises phosphate by 0.05 mg/L. To target a specific phosphate level, increase dose according to the following formula: 0.31vn=m where v= volume of tank in liters, n=desired phosphate increase, and m= volume of product to use in ml. For example, to raise 160 liters by 0.05 mg/L phosphate you would use 0.31*160*0.05 resulting in 2.5 ml to dose. For reference: 1 US gallon=3.8 L.

Reef Potassium

Potassium is an essential element required in metabolic processes, protein synthesis, and growth of corals and macroalgae. In systems supported with nitrogen and phosphorus supplementation, potassium utilization rates may be increased. Supplementing with Reef Potassium™ provides a targeted means of increasing potassium concentrations effectively without also adding phosphate or dissolved organics.

In many reef aquariums, potassium supplementation can enhance coral and macroalgae growth and color – particularly red and pink colors in corals.

Reef Potassium™ is ideally suited for use with an aquavitro® sentia™ dose doser to maintain potassium at consistent concentration based on your aquarium's unique demand but is easily dosed manually as well. Ideal potassium levels will vary but generally range from 380 - 400 mg/L potassium. Reef Potassium™ contains 10% elemental potassium. Use Reef Nitrogen™ and Reef Phosphorus™ to maintain optimal nitrogen and phosphorus levels.

Directions -

Beginner

Use 1 cap (5 mL) per 160 L (40 US gallons) twice a week or as needed to maintain desired potassium levels.

Advanced

The beginner dose raises potassium by 3 mg/L. To target a specific potassium level, increase dose according to the following formula: 0.01vn=m where v= volume of tank in liters, n=desired potassium increase, and m= volume of product to use in ml. For example, to raise 160 liters by 3 mg/L potassium you would use 0.01*160*3 resulting in 5 mL to dose. For reference: 1 US gallon=3.8 L.
