Tropic Marin Plus-NP 250mL – Nitrogen & Phosphorus Additive for Reef Aquariums
Tropic Marin Plus-NP – Balanced Nitrogen & Phosphorus for Healthy Coral Growth
Tropic Marin Plus-NP is a highly concentrated nitrogen and phosphorus supplement designed to prevent nutrient deficiencies in ultra-low nutrient reef aquariums (ULNS).
Modern reef systems with powerful filtration can often strip nitrate and phosphate to undetectable levels. While low nutrients are desirable, prolonged deficiency can negatively affect coral growth, coloration, and overall vitality — and may even encourage nuisance organisms like dinoflagellates.
Plus-NP provides nitrogen and phosphorus bound to an organic energy source, allowing corals and beneficial bacteria to utilize nutrients more efficiently while minimizing waste through denitrification and adsorption.
Suitable for reef aquariums stocked with SPS, LPS, and soft corals.
