Vanadium (V) is a significant trace element in seawater, playing an extremely important role in the physiological and ecological dynamics of marine organisms, including algae, corals, and microbes. It is the second most abundant transition metal in seawater, mainly existing as vanadate (VO₄³-). Its levels fluctuate with seasons and redox conditions, affecting its bioavailability. As per Reef Zlements mixing classification Vanadium is a Type A element. 1 ml of Vanadium Zlement increases the Vanadium concentration of 100 litres by 6 μg/l.
