Highly concentrated solution for adding copper if there are deficits in the aquarium.
Copper is a transition metal that plays an important role in metabolism as a trace element, e.g. in eliminating oxygen radicals. It brightens coral colors and makes the pocilloporin pigments in pink and blue glow. In the sea, it occurs in low concentration levels of up to 3 μg/l. In an aquarium, measured values of up to 10 μg/ l (ppb) are considered harmless, as it is not completely bioavailable.
