Low Alkalinity
Low Alkalinity — Low-alkalinity source water (rainy season, well water), high shrimp absorption during molting, or dilution from heavy rain.
Symptoms
Alkalinity < 80 ppm: strong daily pH swings, molting difficulty, thin/soft shell, scattered post-molt mortality.
Risk Level
Alkalinity < 60 ppm is critical — severe stress, Vibrio/EMS risk.
Treatment Protocol
1. Immediate alkalinity boost: ALKA UP 2-4 kg/1,000m³, apply early morning.
2. Maintain 120-150 ppm (vannamei), 80-120 ppm (monodon).
3. Recheck after 4-6h, add more if needed.
4. Minerals: GROWMIN, MIXBOOM regularly.
5. Long-term: CELL CANPHOS GOLD every 3-5 days.
