The Nyos Calcium Test Kit is a high-sensitivity titration test designed specifically for saltwater aquariums. Engineered for laboratory-level precision, it allows reef hobbyists to accurately monitor calcium levels and maintain the stable water chemistry essential for healthy coral growth and long-term reef success.

Laboratory-Level Accuracy

Measure calcium concentrations with precision down to 5 ppm (mg/L) increments. The highly sensitive titration method delivers reliable results you can trust when managing demanding reef systems.

Designed for Saltwater Aquariums

Unlike generic test kits, the Nyos Calcium Test Kit is formulated specifically for saltwater conditions, accounting for the unique chemistry found in marine aquariums.

Sharp and Easy-to-Read Color Change

Separate indicator and titration solutions create a distinct color transition, making it easier to identify the endpoint and improve testing consistency.

Precision Dosing Components

Includes a precision dosing tip and calibrated measuring equipment designed to ensure repeatable results from test to test.

Consistent, Reproducible Results

Manufactured with strict quality control standards, calibrated droppers, and high-quality reagents to provide dependable measurements every time you test.

Made in Germany

Reagents are produced in Germany according to EN ISO 9001 standards and verified against recognized analytical standards for quality and consistency.
