Bromine is present in water with a concentration of 65 ppm. It therefore falls in the category of most abundant elements.
Hard corals use Bromine for the synthesis of chromoproteins and for the construction of the skeleton. Zooxanthellae then use a small amount of Bromine for the synthesis of photosynthetic enzymes. To obtain the best colouration the concentration of Bromine should be kept as close to natural levels, as slightly lower concentrations dramatically reduce the amount of Bromide tat the coral can use.
1ml of Bromine in 100 litres of water increases the Bromine level by 1.23ppm.
