Supplement contains over 20 concentrated amino acids. This is essential additive for marine aquarium, especially for Ultra Low Nutrient Systems (ULNS). Amino acids are one of the main sources 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.

Amino acids are very easily removed by skimming process, ozone or granulated carbon. Regular dosing is highly recommended. Dosage: 1 drop per 100l (27 US gal) Every other day when the light is off.
