Unstable pH, high toxic gases — that's a lost crop.
Every pond has sludge, but the losing pond lets sludge control it. NH3, NO2, H2S rise without warning — when shrimp surface, it's already too late. Than Vuong probiotic solutions treat the root: clean bottom, stable water, toxic gases never get a chance to accumulate.
Bad water and dirty bottoms in shrimp ponds are usually caused by accumulated organic sludge, excess feed, and dying algae — leading to rising NH3, NO2, H2S. Treat by combining bottom-decomposing probiotics (SOILMAX), algae-cutting enzymes (OZYME), and toxic gas neutralizers (MAX 4000). Avoid harsh chemicals when shrimp are already stressed.
Quick Summary
Main Causes
- Sludge accumulation
- Weak bottom microbes
- Algae bloom or crash
Signs
- excess feed, feces, dead algae sink and decompose anaerobically, producing H2S, NH3
- insufficient aerobic bacteria to decompose organics, nitrogen cycle broken
- mass algae death causes oxygen drop, sudden NH3 spike
Solutions
- Emergency detox
- Treat pond bottom
- Specific NO2 removal

Emergency detox — apply YUCCA or YUCCA C to absorb NH3, H2S immediately, rescue surfacing shrimp
Treat pond bottom — use SOILMAX New to decompose organic sludge, reduce H2S, cut toxic gas at source
Specific NO2 removal — use MAX 4000 specialized NO2 probiotics, safe nitrogen conversion
Cut algae if needed — use OZYME enzymes to cut algae bloom, clean liner slime
Stabilize minerals — add GROWMIN or MIXBOOM to stabilize alkalinity, pH, promote good water color
Maintain probiotics — apply SOILMAX New + MAX 4000 every 3-5 days to maintain water quality
Expected Results
Acute symptoms reduce, shrimp stabilize
Clear improvement, shrimp resume eating
Full recovery, maintain with regular probiotics

What NH3 level is dangerous for shrimp?
NH3 above 0.1 mg/L causes stress, above 0.3 mg/L can be lethal. Apply YUCCA immediately when NH3 exceeds 0.1 mg/L and treat the root with SOILMAX New + MAX 4000 probiotics.
How long does it take to reduce high NO2?
With MAX 4000 specialized NO2 probiotics, usually 2-3 days for noticeable reduction. Use starting dose 200g/1,000m³ for 3 consecutive days, then maintain every 3-5 days.
How to treat pH drop after heavy rain?
Step 1: apply YUCCA to absorb toxins. Step 2: add GROWMIN or MIXBOOM to raise alkalinity, stabilize pH. Step 3: apply SOILMAX New probiotics after 6-12 hours.
How to handle sudden algae crash?
Apply YUCCA + run aerators at max to supply oxygen. Use OZYME to break down dead algae, after 12h apply SOILMAX New to rebuild microbiome. Add GROWMIN to restore water color.
How often should bottom probiotics be applied?
Every 3-5 days with SOILMAX New. High-density ponds or after rain should shorten to every 2-3 days. Best time is late afternoon or evening.
Is dark green pond water dangerous?
Dark green water indicates excessive algae bloom, pH may exceed 8.5 in afternoon. Use OZYME to cut algae, combine with SOILMAX New to balance microbiome and prevent sudden algae crash.
