Generic Calcium & Magnesium Test Kit for Coral & Reef — 120 Tests

Overview

In a saltwater reef or coral aquarium, keeping calcium and magnesium levels within a precise range supports vibrant coloration, steady growth, and stable water chemistry. The Generic Calcium & Magnesium Test Kit is designed to deliver clear endpoint readings you can rely on during routine maintenance.

Readings are presented with vivid color changes that are easy to evaluate at a glance, reducing guesswork during busy days in the reef room. The kit’s compact size lets you store it with your other testing supplies and run up to 120 checks without frequent replenishment.

What you measure

• Calcium (Ca) level: 310–500 ppm with a resolution of 5 ppm per 0.01 mL of the reagent syringe.
• Magnesium (Mg) level: 30–1500 ppm with a resolution of 15 ppm per 0.01 mL of the reagent syringe.
• Test capacity: up to 120 individual measurements per kit.

Color endpoints that stand out

• Calcium endpoint shifts from pink to blue, delivering a crisp, quick read.
• Magnesium endpoint shifts from orange to green, with similar readability.
• High-contrast colors help reduce interpretation time in dim or busy reef rooms.

Why choose this kit

Designed for reef keepers who want straightforward, repeatable results, this kit prioritizes ease of use and value without sacrificing trust in the numbers. It’s a practical tool for ongoing monitoring as you adjust your tank’s chemistry and observe changes in corals, water parameters, or livestock appearance.

How to use (quick guide)

• Collect a small water sample and prepare the syringe with the recommended reagent steps.
• Add reagents following the included instructions and observe the endpoint color shift.
• Compare your color to the chart and record the reading for your reef log or planner.
