Top 4 Signs Your Reef Tank Needs Calcium Supplementation
- Slow Coral Growth: Hard corals showing stunted or minimal skeletal development despite proper lighting and flow
- Low Calcium Test Results: Water tests consistently showing calcium levels below 400 ppm
- Coral Tissue Recession: SPS corals displaying tissue loss or bleaching at the base of colonies
- Poor Coralline Algae Growth: Lack of purple coralline algae development on rocks and glass surfaces
Professional reef keepers recommend testing calcium levels weekly and maintaining consistent supplementation schedules. Premium calcium additives like Aquaforest CA Plus provide the reliability and purity needed for long-term reef success.
