Keep your reef aquarium water testing accurate and consistent with Hanna Marine Alkalinity Checker Reagents (HI772-26). Specifically designed for the Hanna HI772 Marine Alkalinity Checker, these genuine replacement reagents provide enough solution for 25 alkalinity tests, helping you maintain stable water chemistry in your saltwater aquarium.
Alkalinity, also known as carbonate hardness (dKH), is one of the most important parameters to monitor in a reef tank. It plays a crucial role in maintaining stable pH levels and supporting healthy coral skeletal growth. Regular testing helps you track alkalinity consumption and make informed adjustments to your aquarium's dosing routine.

Why Is Regular Alkalinity Testing Important?
Maintaining stable alkalinity is essential for successful reef keeping, particularly in aquariums containing growing stony corals.
As corals build their calcium carbonate skeletons, they consume alkalinity from the surrounding water. Without regular monitoring and supplementation, alkalinity levels can gradually decrease, potentially affecting coral growth and overall reef stability.
Regular testing allows you to:
-
Monitor daily alkalinity consumption.
-
Fine-tune calcium reactor or dosing pump settings.
-
Identify changes in water chemistry before they become problematic.
-
Maintain consistent conditions for healthy coral growth.
The Hanna HI772 Checker provides clear digital readings, making it easy to monitor your reef aquarium's alkalinity without relying on traditional colour-matching charts.
Important Compatibility Information
These reagents are designed for use with the Hanna HI772 Marine Alkalinity (dKH) Checker HC. They are also compatible with the Hanna HI755 Marine Alkalinity Checker, which displays results in ppm.
Please Note: This product contains replacement liquid reagents for 25 tests. The Hanna Checker testing device is sold separately.
