Tropic Marin Plus-NP is a liquid concentrate for supplying important nutrients for corals. In order to thrive, corals require certain minimum concentrations of phosphates and nitrogen compounds for their metabolism and the metabolism of their zooxanthellae. Aquariums that are very low in nutrients (ULNS = ultra low nutrient system) are particularly prone to a lack of these compounds. Tropic Marin Plus-NP provides these phosphates and nitrogen compounds in concentrations that are tailored to the coralsneeds. As they are bound by an organic energy source, nitrogen and phosphates can be utilized by corals more efficiently than inorganic nutritional salt additives. This approach minimizes the loss of nutrients caused by denitrification and adsorption, prevents nutrient deficiency in the corals and restores growth. The liquid concentrate Tropic Marin Plus-NP is easy to use and is suitable both for manual dosing and for dosing pumps.Tropic Marin Plus-NP+ a highly concentrated phosphate and
