Tropic Marin Phos-Feed can be added at any time of the day or night. Since the application clouds the water somewhat and to take advantage of the corals' nocturnal polyp opening, Tropic Marin Phos-Feed should preferably be applied around the time the lights are turned off. The temporary turbidity that forms is normal. The water is particularly clear after the turbidity. Half fill a container with approximately 200ml of reverse osmosis water and add the calculated amount of Tropic Marin Phos-Feed. Mix powder and water well by stirring. Pour the suspension into the current of the aquarium and rinse the cup with aquarium water. Dosage: Start with a daily dosage of 1 ml Tropic Marin Phos-Feed per 200 l (50 US-gal) aquarium water. If after four weeks a phosphate concentration between 0.05 ppm and 0.15 ppm is not reached in the aquarium, double the dosage to 2 ml (larger measuring spoon) per 200 l (50 US-gal). We recommend not to exceed a maximum dosage of 4 ml per 200 l (50 US-gal).
