Description
Reef Zlements Cobalt (150ml) is a high-purity trace element supplement formulated to restore and maintain cobalt levels in reef aquariums. Naturally present in low concentrations in the ocean (ranging from 0.002 µg/l to 0.39 µg/l), cobalt is an essential component of vitamin B12 and plays a fundamental role in DNA and cellular processes. It also acts as an important nutrient for macroalgae growth.
Cobalt may be a limiting factor in bioavailability in oceans, making it vital to monitor and replenish levels in reef aquariums through ICP-guided dosing.
