The label protocol is generic; field conditions are more complex, so this tool adapts the dose to your pond (feed and readings).

🔍 How this is calculated (with your numbers)

The label protocol is generic; field conditions are more complex, so this tool adapts the dose to your pond (feed and readings).

  1. Biomass = 90 PL/m² × 10.000 m²/ha × 80% × 10 g ÷ 1000 = 7,200 kg/haLive shrimp weight per hectare: the base of everything else.
  2. Feed = 7,200 kg/ha × 3% = 216.0 kg/ha/dayFeed drives the nitrogen and organic load (uneaten feed, faeces, sludge) that Bacillus has to work on.
  3. Base dose = k_feed 1.85 × 216.0 = 400 g/ha/week Placeholder – set from Blueweight trials · not validatedk_feed is set so a typical case (90 PL/m², 80%, 10 g, 3%/day = 216 kg feed/ha/day) gives 400 g/ha/week, the middle of the label range.
  4. Reading multipliersBad readings mean more organic load or sludge, so the dose steps up. Normal readings leave it unchanged.
    • Nitrite = 0.5 → normal (Alert ≥ 1, Critical ≥ 5) → ×1 Placeholder – set from Blueweight trials · not validated
    • Sulfide = 0 → normal (Alert ≥ 0.05, Critical ≥ 0.2) → ×1 Placeholder – set from Blueweight trials · not validated
    • Phosphate = 0.5 → normal (Alert ≥ 1, Critical ≥ 3) → ×1 Placeholder – set from Blueweight trials · not validated
    • Org. carbon = 1 → normal (Alert ≥ 2, Critical ≥ 4) → ×1 Placeholder – set from Blueweight trials · not validated

    Total = ×1.000 → 400 × 1.000 = 400 g/ha/week

  5. Cap: maximum 1000 g/ha/week → not reached → 400 g/ha/week Placeholder – set from Blueweight trials · not validatedDefault = 2 × label maximum 500, as the label allows doubling for high organic load on technician advice.
  6. Tablets = 400 g/ha × 1 ha ÷ 2 g = 200 tablets/week; ÷ 1 = 200 tablets/applicationEach tablet weighs 2 g (label). Rounded up to whole tablets.
  7. Label comparison: 300–500 g/ha/week (10–35 PL/m², double for high organic load per technician) → ✓ Within label · Label covers 10–35 PL/m²; this density is outside that range.
  8. Cost analysis: 400 g × $0.00/kg ÷ 1000 = $0.00/ha/week; × 16 weeks = $0.00/ha; × 1 ha = $0.00; per application = $0.00 × 1 ÷ 1 = $0.00
