1. Clinical Overview & Background
Quick Lime (CaO) is a essential water and soil conditioner used for rapidly raises ph, kills pathogens, and eliminates pests in pond bottom..
Proper application timing and dosage accuracy are vital to prevent sudden plankton crashes or chemical toxicity in culture ponds.
4. Step-by-Step Action Protocol
Measure exact dosage based on water volume: 200–500 kg/ha during pond prep..
Pre-dissolve the required quantity in a clean 200L plastic drum containing fresh pond water.
Broadcast uniformly across the pond surface in front of operating paddlewheel aerators for maximum distribution.
Apply during During pond drying phase, especially if soil pH is acidic (< 6.0). for peak biological efficacy.
5. Water Parameters & Dosage Benchmarks
| Parameter / Item | Recommended Value | Operational Importance |
|---|---|---|
| Recommended Dosage | 200–500 kg/ha during pond prep. | Effective chemical threshold |
| Application Timing | During pond drying phase, especially if soil pH is acidic (< 6.0). | Optimal environmental conditions |
| Safety Precaution | Generates high heat when mixed with water. Do not apply during culture with shrimp/fish present. | Prevents crop stress & toxicity |
7. Frequently Asked Questions
Q: Can I mix Quick Lime with probiotics on the same day?
No. Disinfectants or harsh chemicals kill beneficial probiotic bacteria. Wait at least 24–48 hours post chemical treatment before applying probiotics.
Q: How soon after application can aerators be turned off?
Keep all paddlewheel aerators running for at least 2 hours post-application to ensure uniform water mixing.
