Algae Crash / Algae Collapse
Algae Crash / Algae Collapse — Caused by weather changes (heavy rain, overcast), chemical overdose, strong pH swings, or algae overgrowth followed by crash.
Symptoms
Sudden water color change (green → clear or dark brown), morning pH drops sharply, shrimp surface, low DO, excessive foam, foul smell.
Risk Level
Very dangerous — dead algae decompose → NH3, H2S spike → mass mortality within 24-48h if untreated.
Treatment Protocol
1. Maximum aeration 24/7.
2. Broadcast OZYME to break down dead algae.
3. Detoxify: YUCCA C, YUCCA GRO.
4. Re-seed probiotics: SOILMAX or MAX 4000 after 12h.
5. Stabilize pH: ALKA UP if pH < 7.5.
6. Reduce feeding 50-70% for 2-3 days.
