Brightwell Aquatics Calcion 500ml – Calcium Supplement for Reef Aquariums

Brightwell Calcion is a highly concentrated liquid calcium supplement formulated to restore and maintain optimal calcium levels in marine aquariums. Ideal for systems with SPS/LPS corals, mollusks, and other calcifying invertebrates, Calcion delivers bioavailable calcium without affecting alkalinity or introducing unwanted contaminants.

🌊 What Is It Used For?

Calcium is vital for the skeletal growth of corals, shells of mollusks, and other reef-building organisms. Natural seawater maintains calcium levels between 400–450 ppm. Over time, calcium depletes due to biological processes, and Calcion safely replenishes it—ensuring healthy growth, vibrant coloration, and structural strength.

✅ Key Benefits

✔ Promotes Coral Calcification: Supports robust skeleton formation and polyp expansion
✔ Does Not Alter Alkalinity: Formulated to maintain water chemistry balance
✔ Phosphate & Silicate Free: No unwanted additives or contaminants
✔ Fast Absorption: Liquid form ensures even distribution and rapid availability
✔ Supports Ionic Balance: Ideal for use with magnesium and alkalinity dosing

🧬 How to Use

1. Test Calcium Levels: Use a reliable test kit to determine current ppm

2. Dose: Add 5 mL per 100 L (26 gal) to raise calcium by 5 ppm

3. Disperse Properly: Apply in a high-flow area (e.g., near pump or sump)

4. Monitor & Adjust: Dose daily or as needed based on coral demand

⚠️ Do not increase calcium by more than 20 ppm per day to avoid destabilizing the system.
