Reef Zlements Z-pHplus Part 2 – Calcium & Magnesium (2.5 Litres)

Reef Zlements Z-pHplus Part 2 is the calcium, magnesium, and trace element component of the Z-pHplus two-part dosing system, formulated specifically to support reef aquariums running at elevated pH levels. Used in conjunction with Z-pHplus Part 1, it delivers balanced calcium supplementation while maintaining ionic stability and optimising coral growth.

Each litre contains 71,000 ppm of calcium, alongside magnesium and a carefully balanced blend of micro and trace elements formulated for high-pH reef environments. This targeted elemental ratio supports strong skeletal formation, metabolic function, and sustained coral health while reducing the need for additional trace dosing.

When dosed as recommended, Z-pHplus maintains ionic balance and has been shown to promote up to 2× faster coral growth compared to traditional dosing methods. Testing has proven Z-pHplus to be more effective than Kalkwasser or CO₂ scrubbers at raising and maintaining aquarium pH, making it an ideal solution for systems with a pH of 8.15 or below.

Produced under strict laboratory quality control, Z-pHplus Part 2 ensures consistency, purity, and predictable performance.
