Coral Care Guide: Keeping Your Reef Vibrant
Adding coral to your saltwater aquarium transforms it into a thriving reef, but corals require specific care to stay healthy and colorful. This guide covers the essentials of coral care for both beginners and seasoned reef keepers.
1. Choose the Right Coral for Your Tank
Not all corals have the same care level. Soft corals (like mushrooms and leathers) are hardy and great for beginners. LPS corals (large polyp stony) need moderate care, while SPS corals (small polyp stony) require stable water chemistry and strong lighting. Always match your coral choice to your experience level.
2. Maintain Stable Water Parameters
Corals are sensitive to changes. Key targets are:
-
Temperature: 76–80°F
-
Salinity: 1.024–1.026 specific gravity
-
pH: 8.1–8.4
-
Alkalinity, calcium, and magnesium must remain balanced to support skeletal growth. Regular water testing is critical.
3. Provide Proper Lighting
Corals rely on photosynthesis from their symbiotic algae (zooxanthellae). Use reef-specific LED or T5 lights and adjust intensity to match coral type. Too much light can bleach corals; too little will stunt growth.
4. Ensure Good Water Flow
Water movement delivers nutrients and removes waste. Soft corals prefer moderate, indirect flow, while SPS corals thrive in stronger, turbulent currents. Use powerheads to create natural, varied circulation.
5. Feed When Necessary
Many corals get energy from light, but some also benefit from supplemental feeding with phytoplankton, zooplankton, or coral foods. Feed sparingly to avoid nutrient spikes in the tank.
6. Watch Placement and Compatibility
Corals can sting or overgrow neighbors. Leave adequate space between colonies, and research compatibility before introducing new species.
Final Tip: Coral care is about stability. With consistent water quality, the right lighting, and mindful placement, your reef will flourish with vibrant growth and color.
