Is Your Lighting Secretly Sabotaging Your Reef?
Your reef lighting could be doing more harm than good if not properly set up. Here’s how to spot the signs and fix them fast:
🚩 Warning Signs
-
Faded coral colour? You might have inconsistent PAR or spectrum shift.
-
Coral bleaching in spots? Could be hot spots or intensity spikes.
-
Persistent algae bloom? Likely caused by excess red spectrum and poor water movement.
✅ Easy Fixes
-
Check your PAR levels (aim for 100–300 PAR for mixed reefs).
-
Gradually tweak your photoperiod—don’t shock your reef.
-
Reduce blue intensity during algae outbreaks.
-
Reposition lights to eliminate shadows and overexposure.
