Maintaining stable alkalinity, calcium, and magnesium is the core discipline of reef keeping, and the margin for error in an SPS or LPS-dominant system is narrow. Hanna Instruments' Marine Coral Care Kit addresses all three parameters with dedicated digital checkers that have been calibrated specifically for marine chemistry ranges, eliminating the ambiguity that comes with color-matching reagent kits.
The HI772 Alkalinity Checker measures carbonate hardness in dKH, providing the data needed to maintain pH stability and support the carbonate skeleton development that corals depend on. For anyone running a two-part or calcium reactor dosing regimen, consistent alkalinity readings are non-negotiable, and the HI772 delivers them quickly and accurately.
The HI758 Calcium Checker covers the 200–600 ppm range typical of marine systems, giving precise ppm readings that are especially valuable when tracking calcium uptake in densely stocked reef tanks. The HI783 Magnesium Checker rounds out the trio, measuring from 1000 to 1800 ppm using the same colorimetric method. Magnesium stabilizes both calcium and alkalinity—an imbalance here can undermine everything else in your dosing routine, often without obvious symptoms until the damage is done.
All three units share the same simple 4-step testing workflow, which makes it practical to run all three tests in a single maintenance session. The kit is a sensible investment for reef keepers who test frequently and want results they can trust without spending time interpreting color gradations under variable lighting.
Overview
Test. Read. Adjust.
Three critical reef parameters, three dedicated digital checkers. The Marine Coral Care Kit gives you accurate numbers on alkalinity, calcium, and magnesium in one package.
Digital Precision
- Colorimetric measurement delivers exact numeric readings
- No color chart interpretation or lighting-dependent guesswork
- Calibrated specifically for marine chemistry ranges
Complete Parameter Coverage
- HI772 measures alkalinity in dKH for carbonate stability
- HI758 reads calcium from 200–600 ppm
- HI783 monitors magnesium from 1000–1800 ppm
Consistent Workflow

Features
Three Checkers, One Kit
The retail packaging shows the Marine Coral Care Kit as sold, combining the HI772, HI758, and HI783 checkers in a single box. Purchasing as a kit covers all three foundational reef parameters without sourcing each checker separately.
