Marine Calcium Checker Reagents, Pack of 25

The HI-758-26 Marine Calcium Checker Reagents provide a fast and accurate method for measuring calcium levels in saltwater aquariums. These high-quality, pre-measured reagents are specifically designed for use with the HANNA INSTRUMENTS Marine Calcium Checker HC, ensuring reliable and consistent results every time.

Utilising the established Zincon Method, the chemical reaction produces a distinct blue tint in the water sample. The process is incredibly simple: first, add 1 ml of the initial liquid reagent to your sample, followed by the entire contents of one second-reagent powder packet from the set. The HI-758 Checker then analyses the resulting colour to determine the exact calcium concentration, displaying the result in parts per million (ppm).

These reagents are optimised for testing marine water samples with an expected calcium range of 200 to 600 ppm, covering the ideal levels required for healthy coral growth and reef aquarium stability. The convenient Pack of 25 provides ample tests for regular monitoring, allowing aquarists to maintain precise water chemistry without guesswork.
