πŸ’§ How to Safely Add Liquid Chlorine to Your Pool

Liquid chlorine (sodium hypochlorite) is a powerful and effective pool sanitizer, but it must be handled with care. This guide will walk you through safe application and best practices for protecting your pool and yourself.


⚠️ Safety First: Wear Proper Protection

Liquid chlorine is 4 to 6 times stronger than standard household bleach. Always use personal protective equipment when handling it:

  • πŸ‘Ÿ Closed-toe shoes (no sandals)

  • 🧀 Rubber gloves

  • πŸ‘– Long pants

  • πŸ₯½ Eye protection

πŸ’‘ If chlorine splashes on your skin, rinse the area thoroughly with clean water immediately.


πŸŒ™ Best Time to Add Liquid Chlorine

Liquid chlorine is unstabilized and will quickly degrade in sunlight. For effective results:

  • βœ… Add after sunset

  • ❌ Avoid daytime application (unless indoors or fully shaded)

  • βœ… Ensure pump is running for circulation


πŸͺœ Step-by-Step Instructions

1. Get Ready

  • Turn on your pool pump

  • Remove pool covers or floating objects

2. Handle the Jug with Care

  • Hold the jug away from your body

  • Extend your arm safely over the pool

  • Never lean so far that you risk falling in

3. Add to the Deep End

  • Slowly pour chlorine into the deep end

  • Keep the jug close to the water to avoid splashing

4. Brush the Pool

  • After dosing, brush the walls and floor

  • This helps:

    • Spread chlorine evenly

    • Kill algae on surfaces

    • Prevent chlorine from settling and damaging the liner

5. Run the System Overnight

  • Keep the pump running overnight

  • Leave the pool uncovered for ventilation


πŸ§ͺ Test Your Chlorine Level the Next Morning

By morning, your free chlorine reading should be:

  • βœ… 1–3 ppm (normal range)

  • πŸ“ˆ Higher if you're treating for algae or shocking the pool

πŸ”Ž If chlorine is at zero, there may be organic load or low stabilizer. Recheck your water chemistry.


πŸ“Œ Important Reminders

  • Store chlorine in a cool, shaded location, away from children and pets

  • Never mix chlorine with other chemicals

  • Do not dilute unless instructed by a pool professional

  • Use a reliable test kit or digital tester for accurate readings
