The Red Sea Calcium Pro Test Kit is an advanced titration test designed to accurately measure calcium levels in marine and reef aquariums. Calcium is an essential element for coral calcification, skeletal growth, and the development of invertebrates such as snails and clams. This test kit delivers highly precise results, making it a critical tool for reef aquarists who want to maintain optimal calcium levels and ensure healthy coral growth and vibrant coloration.
High Accuracy: Measures calcium with a precision of 5 ppm for detailed monitoring
Critical for Coral Health: Supports skeletal formation and strong growth in SPS and LPS corals
Advanced Titration Method: Ensures consistent and reliable results for proper dosing adjustments
Complete Kit: Includes reagents, durable glass vial, titration syringe, and detailed instructions
Long-Lasting: Provides up to 75 tests per kit, offering great value for ongoing reef care
Collect a water sample in the provided glass vial
Add the reagents step by step as instructed in the manual
Use the titration syringe until the color change indicates the calcium concentration
Read the calcium level directly from the syringe scale
Record results and adjust calcium supplementation if required with products such as Red Sea Foundation A (Calcium + Strontium)
Measures in 5 ppm increments
Recommended calcium range for reef aquariums: 400–450 ppm
75 Tests Kit – Includes reagents, glass vial, titration syringe, and instructions
Optimal Range: Maintain calcium between 400–450 ppm for healthy coral growth
Regular Testing: Test 2–3 times per week, especially in tanks with high-demand corals (SPS-dominated systems)
Use with Other Pro Kits: Combine with Red Sea Magnesium Pro and KH/Alkalinity Pro Test Kits for complete reef chemistry management
Stable Parameters: Keep calcium levels stable, as fluctuations can stress corals and reduce calcification
Reef Care Program: An essential part of the Red Sea Reef Care Program for achieving balanced reef conditions
