What causes coral bleaching in home aquariums and how can I fix it?
Quick Answer
Coral bleaching is usually caused by stress from temperature swings, light shock, chemistry instability, or nutrient imbalance. Stabilize conditions gradually and monitor recovery closely.
Coral bleaching in home aquariums is usually a stress response where corals lose the algae that provide most visible color and energy. It can be reversed in many cases if you stabilize quickly and avoid dramatic corrections.
Temperature stability
Temperature stability is critical for bleaching prevention and recovery. Keep changes gradual, log every measurement, and avoid chasing numbers with big swings. Practical step 1: make one adjustment, observe for 24-48 hours, then decide your next move based on tissue color, polyp extension, and feeding response.
Temperature stability is critical for bleaching prevention and recovery. Keep changes gradual, log every measurement, and avoid chasing numbers with big swings. Practical step 2: make one adjustment, observe for 24-48 hours, then decide your next move based on tissue color, polyp extension, and feeding response.
