Reef Zlements Z-pHplus Part 2 – Calcium & Magnesium (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 for reef aquariums running at elevated pH levels. Used alongside Z-pHplus Part 1, it delivers balanced calcium supplementation while maintaining ionic stability and supporting rapid coral growth.

Each litre contains 71,000 ppm of calcium, combined with magnesium and a comprehensive blend of macro, micro, and trace elements optimised for high-pH reef environments. Z-pHplus supplies essential elements including boron, bromide, iodine, strontium, potassium, lithium, magnesium, and many others required for strong skeletal development and long-term coral health.

When dosed as recommended, Z-pHplus maintains ionic balance and has been shown to support 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 ideal for systems with a pH of 8.15 or below.

Produced under strict laboratory quality control, Z-pHplus Part 2 ensures exceptional consistency, purity, and predictable performance in high-consumption reef systems.
