Honey, which is rich in either sugar and amino acids, can be used as carbon source and protein synthesis source. For carbon source, might act as Vodka, should be helpful in removing nitrate and phosphate. As for the protein synthesis source, amino acids are essential compositions of proteins. Since the colors of the corals are lights emitted from the fluorecent proteins in the corals, providing sufficient amino acids should be efficient for the protein synthesis. The more the fluorecent proteins inside the corals, the intenser the color of the corals.
This is suggested and tested by myself. Any question or comment are welcome to discuss here!
How much do you dose and any negatives when you started in the beginning?
