Calcium is a critical element for maintaining a healthy reef aquarium. Reef invertebrates like corals, crustaceans, mollusks, and certain encrusting algae rely on calcium for growth and overall health. As these invertebrates use the calcium present in aquarium water, calcium levels gradually decrease, making it important to regularly monitor and adjust levels to keep your reef thriving.

This Calcium Test Kit allows you to easily and accurately measure calcium levels in your reef aquarium, ensuring optimal conditions for your invertebrates. It measures calcium levels as low as 20mg/L using a reliable titration method, which features an easy-to-see color change for precise measurements.

Key Features:

• Accurate Measurement: Measures calcium levels as low as 20mg/L for precise monitoring.
• Titration Method: Provides easy-to-see color change for highly accurate readings.
• Essential for Reef Health: Ideal for maintaining proper calcium levels for corals, crustaceans, mollusks, and algae.
• Easy to Use: Designed for reef aquarium use, allowing aquarists to effortlessly maintain calcium levels.

Ensure the health and growth of your reef aquarium inhabitants by regularly testing and maintaining proper calcium levels with this easy-to-use kit.
