Agricultural Lime (CaCO₃)

210 kg

Application Method

Split into 2–3 daily applications

Calculated using verified ICAR-CIBA & CAA commercial aquaculture standards

How the Formula Works

Lime (kg) = Pond Area (acres) × (Target pH - Current pH) × 200 kg

Why This Calculation Matters:

Maintaining stable pH between 7.5 and 8.3 prevents toxic un-ionized ammonia spikes and promotes healthy diatom blooms.

Pro Farming Tips:

  • Apply lime early in the morning when pH is at its daily lowest point.
  • Use Agricultural Lime (CaCO₃) or Dolomite [CaMg(CO₃)₂] for routine adjustments. Use Quicklime (CaO) only for emergency pond bottom disinfection.
