API Calcium Test Kit is a reef aquarium calcium testing kit designed to help you monitor calcium levels in water used by corals, crustaceans, and other invertebrates. In reef setups, calcium is used over time, so levels can drop as the aquarium becomes more biologically active. This test kit uses a titration method to let you check your current calcium level and stay on top of maintenance decisions based on measured results.
Features:
- Titration-style calcium test for practical, hands-on water monitoring
- Helps track calcium depletion that can occur in a busy reef aquarium
- Measures calcium down to 20 mg/L for useful detection of low-range levels
- Includes detailed instructions to guide you through performing the test correctly
- Includes a user-friendly color chart to help interpret results
