Basic Coral Care 基礎珊瑚養護指南

Keeping corals healthy begins with understanding their essential needs — light, water flow, and stable water chemistry. Once you master these fundamentals, your reef will naturally thrive.
要讓珊瑚健康成長，首先要了解牠們的三大需求——光線、水流與穩定的水質。只要掌握這些基本功，缸內生態就能自然穩定地發展。

1. Lighting｜光照
Corals depend on their symbiotic algae (zooxanthellae) to photosynthesize. Use high-quality reef lights such as LED, T5, or hybrid systems. When adding new corals, gradually increase light intensity to avoid bleaching.
珊瑚透過共生藻類（zooxanthellae）進行光合作用。建議使用高品質的LED、T5或混合燈具。新增珊瑚時要循序漸進地增加光照強度，以免造成白化。

2. Water Flow｜水流
Proper flow removes debris and brings oxygen and nutrients. SPS corals prefer strong, random flow, while LPS and soft corals enjoy gentler, rhythmic movement.
良好的水流能幫助清除雜質並帶來氧氣與營養。SPS珊瑚偏好強而不規則的水流，LPS與軟體珊瑚則適合溫和有節奏的流動。

3. Water Parameters｜水質參數
Stability is more important than perfection.
與其追求完美數值，不如保持穩定：
Temperature｜溫度：24–26°C
Salinity｜鹽度：1.025–1.026 SG
Alkalinity｜鹼度：7–9 dKH
Calcium｜鈣：400–450 ppm
Magnesium｜鎂：1250–1350 ppm
Nitrate｜硝酸鹽：1–10 ppm
Phosphate｜磷酸鹽：0.02–0.08 ppm

4. Acclimation｜適應過程
Drip acclimate new corals to match your tank’s temperature and salinity slowly. Rapid changes may cause stress or tissue damage.
新增珊瑚時，使用滴流式適應法慢慢調整溫度與鹽度。太快的變化可能導致組織損傷或壓力反應。

5. Observation｜觀察
Your eyes are your best tools. Healthy corals extend their polyps and display vibrant colors. If you notice retraction or fading, check lighting and water quality immediately.
觀察是最好的工具。健康的珊瑚會有良好的觸手伸展與鮮豔色彩。若出現縮觸或退色，請立即檢查光線與水質。


💡 Practical Tips｜實務建議
Test your water weekly and log the results — trends matter more than single readings.
每週測試水質並記錄數據，趨勢比單次數值更重要。
Change 5–10% of your tank water regularly to replenish trace elements.
定期更換5–10%的缸水，可補充微量元素。
Avoid sudden system changes — corals love consistency.
避免劇烈變動，穩定才是珊瑚最愛的環境。
