Nyos Reefer Alkalinity Test Kit – Carbonate Hardness (KH) Testing

Nyos® Reefer Carbonate Hardness / Alkalinity Test Kit delivers laboratory-grade precision for measuring alkalinity (KH) in marine aquariums. Stable carbonate hardness is one of the most critical parameters for coral health, calcification, and pH stability—yet it’s notoriously difficult to measure accurately in seawater due to interfering ions.

Developed specifically for reef conditions, this test kit provides highly precise and reproducible results you can rely on. Manufactured in Germany under strict quality control, Nyos Reefer test kits combine professional-level accuracy with an outstanding price-to-performance ratio, making laboratory-quality testing accessible to everyday reef keepers.

Clear pictogram instructions and calibrated droppers ensure ease of use and consistent readings every time.
