The Acids Amino Acid Blend from Polyplab is a highly concentrated mixture of specific amino acids designed to enhance coral growth and coloration in saltwater reef aquariums. This blend contains only those amino acids that have been scientifically proven to improve the health and appearance of corals, while excluding any that could inhibit their growth. Each daily dose of one drop per 25 gallons directly benefits your tank's inhabitants by providing essential nutrients often lacking in low-nutrient environments.
