Highly concentrated solution for adding zinc if there are deficits in the aquarium.
As a transition metal, zinc is associated with key substance conversions by enzymes. It plays a particularly crucial role in the uptake of carbon and phosphate and the conversion of these macronutrients. The need for zinc is especially high when bacteria and artificial decorative materials are used. In the sea, it occurs in very low concentration levels of 2-5 μg/l (ppb).
