Highly concentrated solution for adding nickel if there are deficits in the aquarium.
Nickel is a transition metal and, as a trace element, it enhances coral growth. It deepens and strengthens coral coloration (red + turquoise) by improving the absorption of nitrogen compounds. Basal disk formation can be problematic if the nickel content is too low. Bright colors and sharp contrasts are also difficult to achieve without nickel. In the sea, it occurs in very low concentration levels of 0.5 - 2 μg/l (ppb).
