To thrive, corals need certain concentrations of phosphates and nitrogen compounds necessary for their metabolism and that of their zooxanthellae. In particular, aquariums with extremely low nutrient conditions ( ULNS = Ultra low nutrient system = oligotrophic systems) may have a lack of these nutrients.
Thanks to Tropic Marin ® Plus-NP , corals benefit from phosphates and nitrogen compounds in concentrations that meet their needs. Bound by an organic energy agent, nitrogen and phosphates are more easily assimilated by corals than when inorganic nutrient salts are added. This helps to minimize nutrient losses due to denitrification and adsorption, prevent coral nutrient deficiency, and get corals back on the growth path.
Plus-NP Liquid Concentrate is easy to use and suitable for both manual dosing and dosing pumps.
Advantages :
| • | highly concentrated solution of phosphates and nitrogen used to combat nutrient limitations for corals |
| • | especially suitable for reef aquariums that have low nutrient conditions (oligotrophic systems) |
| • | suitable for stocking with soft corals, LPS and SPS |
| • | simple dosing thanks to the liquid state of the solution |
| • | suitable for both manual dosing and dosing pumps |
Manual :
Turn the pump head to the left until it pops out. Dose 1 ml (1 pump actuation) per 100 l aquarium volume per day until the nutrient limitation of the corals is eliminated. The corals then show normal growth and coloration.
Maximum dosage: 1 ml per 100 l aquarium volume per day.
Suitable for both manual dosing and dosing pumps. Keep the bottle tightly closed, in a cool place away from light!
