HANNA INSTRUMENTS Marine Alkalinity Checker Reagents, Pack of 25

The HANNA INSTRUMENTS HI-772-26 reagents are a pack of 25 high-quality, pre-measured sachets designed for fast and accurate alkalinity testing in marine aquariums. These reagents are specifically formulated for use with the HI-772 Marine Alkalinity Checker HC, providing a reliable and user-friendly method for monitoring crucial water parameters.

Utilising a precise Colorimetric Method, the reagent causes a distinctive colour change in the sample water, transitioning through a range from yellow to green to blue. The user simply adds the pre-measured solution to the sample, and the reaction takes place immediately. The dedicated Marine Alkalinity Checker then analyses the resulting colour to determine the exact concentration, displaying the result clearly in degrees of Carbonate Hardness (dKH).

This system is designed for testing samples with an expected alkalinity range of 0.0 to 20.0 dKH, covering the typical requirements for a healthy reef or marine aquarium environment. Consistent alkalinity is vital for coral growth, buffering pH stability, and overall aquatic health. Each sachet is pre-measured to eliminate measurement errors and ensure consistent, repeatable results every time, making professional-grade water testing accessible to all aquarists.

The compact packaging is designed for convenient storage. With 25 tests per pack, you have a substantial supply for regular monitoring, helping you maintain a stable and thriving marine ecosystem with confidence and precision.
