Reef Zlements Part 2 Universal

Reef Zlements Part 2 Universal is a high-purity calcium and trace element solution designed for reef aquariums using the H₂P two-part dosing system. Developed and manufactured in the UK, this balanced formula delivers essential calcium (~72,000 mg/L), magnesium, and 13 key macro and trace elements, all optimized for coral health, skeletal growth, and ionic stability.
