Description
Calcium+ with Trace is a carefully formulated solution designed to safely raise calcium levels in your reef tank while providing essential trace elements that support coral and invertebrate health. It works best when used in combination with Alkalinity + with Trace and Magnesium+ with Trace, together delivering 18 different trace elements to support a balanced and thriving reef environment.
When added, 1 mL per 100 liters (26 gallons) will increase calcium by approximately 1 ppm. Maintaining stable calcium levels between 420–470 ppm is crucial for strong coral skeleton formation, vibrant coloration, and overall reef stability.
Dosing Guidelines
- Standard Dose: 1 mL per 100 liters (26 gallons) → increases calcium by ~1 ppm
- Recommended Increase: Raise calcium gradually at a rate of 20–30 ppm per day until the desired level is reached
- Maintenance Dose: Once desired levels are achieved, reduce to a lower maintenance dose
- Combination Use: Works best alongside Alkalinity+ with Trace and Magnesium+ with Trace for complete trace element support
Application Tips
- Dose into your sump or a high-flow area to ensure even distribution
- Avoid concentrated direct dosing into the display tank to prevent irritation to livestock
- Automated dosing systems provide safe and consistent calcium increases
- Regular testing ensures your calcium and trace element levels stay within optimal ranges
Benefits of Stable Calcium Levels
- Supports strong skeletal growth in corals and invertebrates
- Helps maintain balanced alkalinity and magnesium levels for reef stability
- Promotes vibrant coral coloration and overall coral health
- Reduces stress caused by sudden fluctuations in calcium or other minerals
Community Benefits
Using Calcium+ with Trace in combination with Alkalinity+ with Trace and Magnesium+ with Trace provides your reef tank with 18 essential trace elements, helping to foster a resilient and visually stunning reef community. Balanced calcium, alkalinity, and magnesium levels support healthy corals, thriving fish, and stable microfauna populations.

Calculation Results
Calculation Algorithm
Solution strength is defined in the schema as ppm increase per 1 mL per 100 L.
mL required = (Target ppm - Current ppm) × Volume(L) ÷ (Solution strength × 100)
Dosing is split to avoid raising calcium by more than 50 ppm per dose.
Alkalinity+
Alkalinity+ is a vital reef supplement that stabilizes pH and supports strong coral skeleton formation by replenishing carbonate hardness (dKH) in your aquarium. Enriched with key trace elements, it promotes balanced water chemistry, enhances coral growth, and helps prevent sudden swings that can stress reef inhabitants. Consistent dosing of Alkalinity+ provides the foundation your reef needs for long-term stability and vibrant health.
Magnesium+
Magnesium+ is a balanced reef supplement formulated to stabilise calcium and alkalinity levels while promoting optimal coral health. By replenishing essential magnesium along with vital trace elements, it helps prevent fluctuations that stress corals and supports strong skeletal growth. Regular use of Magnesium+ enhances natural coloration, boosts resilience, and ensures your reef system maintains the stability it needs to thrive.
