In Acropora systems, maintaining strong skeletal growth and vibrant coloration often comes down to fine-tuning the trace elements that most reefkeepers overlook. Fluoride is one of those quiet essentials. When levels fall too low, coral structure can weaken and blue or purple hues begin to fade. Reef Charge Fluoride⁹+ restores balance through precise, controlled supplementation designed specifically for SPS-dominant aquariums.
Why Fluoride Matters for Acropora
Fluoride supports the natural mineral structure of coral skeletons and has been closely linked to enhanced blue and purple pigmentation in Acropora. Stable levels help corals deposit calcium more efficiently, improving skeletal density and growth-tip strength. In systems where trace elements are depleted or aggressively filtered, fluoride can gradually fall below optimal levels, reducing color vibrancy and growth consistency.
Supplementing with Fluoride⁹+ helps bring this key trace element back into balance, encouraging deeper coloration and healthier skeletal development in fast-growing SPS corals.
About Reef Charge Fluoride⁹+
Fluoride⁹+ is a concentrated trace supplement formulated for occasional correction, not daily dosing. It provides a reliable way to restore fluoride levels in systems that show depletion through ICP testing or visible color loss. Every batch is produced to laboratory standards for consistency and safety, ensuring your corals receive the precision they need without unnecessary additives.
- Supports Acropora skeletal growth and blue/purple color intensity
- Ideal for SPS-dominant or low-nutrient reef systems
- Designed for occasional use following ICP testing
When and How to Dose
Because fluoride is required only in trace amounts, it should always be added conservatively. Dose in a high-flow area and allow at least 24 hours before re-testing. Most reefkeepers find that small, periodic adjustments are all that’s needed to maintain consistent coloration and skeletal integrity.

Example dosing for a 100 gal tank:
+0.05 ppm → 2 mL
+0.10 ppm → 4 mL
+0.20 ppm → 8 mL - Do not increase fluoride by more than 0.2–0.3 ppm per day
Safe Handling
- For aquarium use only
- Avoid skin and eye contact; rinse thoroughly with water if exposed
- Keep away from children and pets
How It Fits into Your Reef Routine
Fluoride⁹+ is a valuable tool for reefkeepers chasing both growth and color perfection. Once major parameters like calcium, alkalinity, and magnesium are stable, trace adjustments refine coral health and appearance. Regular ICP testing followed by small, targeted corrections with Fluoride⁹+ can help restore the crisp blues and deep purples that define a thriving Acropora reef.
Final Thoughts
Trace management is where the difference between good and exceptional SPS systems is often found. Reef Charge Fluoride⁹+ offers reefkeepers precise control over a critical but often overlooked element that directly influences color and skeletal strength. Use as a correction after testing, and let your Acropora reveal the results under full spectrum light.
