Bio-Zone Intech

1. Product description
- Bio-Zone Intech is Navico's new-generation probiotic, combining 2 high-density Bacillus strains with a biological enzyme system specialized for intensive shrimp - fish ponds.
- The product helps rapidly decompose organic sludge, dead algae, and excess feed at the pond bottom, control toxic gases, stabilize water color and microflora, thereby reducing stress, limiting pathogenic Vibrio, and protecting shrimp and fish from fry to harvest stage.
- Suitable for: earthen ponds, lined ponds, high-tech ponds, whiteleg shrimp, black tiger shrimp, pangasius, tilapia, snakehead fish.

2. Active ingredients
- Bacillus subtilis, Bacillus licheniformis - Density > 5x10⁹ CFU/g
- Biological enzymes: Protease, Amylase, Cellulase to support decomposition of protein, starch, and fiber in bottom sludge
- Excipients q.s. 1 kg
- Fine powder form, fast dissolving, no surface scum, no shock to aquatic animals.

3. Functions & benefits
- Pond-bottom sludge treatment: decomposes leftover feed, shrimp/fish feces, dead algae, reduces bottom slime, black sludge, and bottom odor.
- Toxic gas control NH3 / NO2 / H2S: reduces toxic gases after rain, when ponds are rich in organics, shrimp gasping at surface or gathering at pond banks.
- Stabilizes microflora, inhibits Vibrio: competes for adhesion sites and nutrients, helping to outcompete bacteria causing hepatopancreatic disease, white feces, black spots.
- Stabilizes water color: maintains tea-brown and young banana-leaf green color, limits dead algae, algae crash, and slimy water.
- Increases dissolved oxygen, reduces stress, helps shrimp molt evenly, eat strongly, grow fast, and reduce FCR.

4. Directions for use
Activation:
Dissolve 1 pack in 50 liters of clean pond water, aerate vigorously continuously for 2-4 hours before broadcasting to activate the probiotics. Spread evenly over the pond surface at 8-10 AM, in light sunshine, with paddlewheels / aeration on.

Recommended dosage:
- Regular prevention: 500g / 5,000 - 8,000 m³ of water, every 5-7 days
- Dirty ponds, heavy bottom slime, high toxic gases: 500g / 3,000 - 5,000 m³, for 2-3 consecutive days, then maintain regularly
- After heavy rain, 48 hours after disinfection: use double the preventive dose to restore microflora
- Dosage may be adjusted according to stocking density, age of shrimp/fish and actual pond conditions. Navico technicians will advise a protocol for each crop.

5. Precautions
- Do not use together with antibiotics or disinfectant chemicals. Separate by at least 48 hours.
- Use in the morning for best organic decomposition efficiency, avoid evening application causing local oxygen deficiency.
- Seal tightly after opening, avoid moisture.

6. Storage & Packaging
- Store in a dry, cool place, below 30°C, away from direct sunlight.
- Shelf life: 24 months from manufacturing date.
- Packaging: 500g / pack
