Supplement contains concentrated amino acids. This is essential complement for marine aquarium, especially for Ultra Low Nutrient Systems (ULNS). Amino acids are one of the main source of energy for all types of corals and filter feeders. It promotes metabolism, aids growth as well as vitality. In natural coral reefs the concentration of total amino acids is low. It fluctuates between 200-500 nmol/l. However the latest scientific research proves that coral can adsorb up to 7 times more amino acids depending on availability. Amino acids are very easily removed by skimming process, ozone or granulated carbon.
