Dosage: 10 drops per 100 liters (27 US gal) of water every other day with an average coral stocking. Do not dilute. Do not mix together with other products in one container. After opening, store in a refrigerator. All coral supplements have a recommended dosage, though, it’s important that each aquarium is different and the dosage may vary depending on the coral cast. We recommend starting dosing foods and supplements from half of the dose (even ¼) and observing the corals and their reactions to the administered food. Once the aquarium shows no sign of overdose, we recommend increasing dosage to the target dose. In order to facilitate the food absorption, SPS and LPS corals should be fed after the light is out. Corals such as Zoanthus, Ricordea and other mushroom corals should be fed during the day. In order to ensure the best nutrients absorption, all supplements and foods for corals should be dispensed directly into the aquarium. During the feeding we recommend switching off the skimmer for about an hour. Once opened store in fridge. Do not overtighten the screw, otherwise the cover might be damaged.
