Corals don’t “randomly” decline—something drifted
When corals recede, bleach, or stay closed, it’s usually a stress response to instability: light shock, parameter swings, pests, or poor flow. The fastest path forward is a calm checklist—not panic changes.
The calm troubleshooting checklist
- Check salinity (top-off consistency)
- Check temperature (daily swings?)
- Test alkalinity (big swings?)
- Review light changes (new bulb/setting?)
- Check flow (dead spots, detritus)
- Inspect for pests (if applicable)
Flow + filtration first
Improving flow and cleaning export often reduces irritation quickly.
