How Much Chlorine to Add to a 1000 Litre Water Tank

For a 1000 litre water tank, one measured Safe chlor chlorine tablet delivers the correct chlorine level to disinfect the water. 

Getting the dose right matters: too little leaves bacteria alive, too much makes the water taste and smell of chlorine.

Here is how to dose it correctly and what it actually costs.

The simple answer

Why Safe chlor is not bleaching powder 

Unlike standard bleaching powder, which lacks stability and leads to unreliable purification due to fluctuating strength, Safechlor chlorine tablets provide a consistent solution. 

Using Safe Chlor chlorine tablet for water tanks eliminates uncertainty, ensuring reliable purification results every time.

How to dose a 1000L tank correctly

  1. Confirm your tank volume. 
  2. Add 1 tablet twice a week.
  3. Wait for 30 minutes. Chlorine needs time to work.
  4. Do not overdose thinking more is safer. The measured dose is the safe dose.

Why this isn't bleaching powder

  • Bleaching powder loses strength and leads to unreliable purification 

  • You are always estimating. No way to know what you actually added.

  • Safe chlor is precise, ensuring reliable purification results every time

Frequently asked questions

How many chlorine tablets for a 1000 litre tank?
 One tablet. Each Safe Chlor tablet is for treating 1000 litres.

 30 minutes. Chlorine needs that contact time to kill waterborne bacteria.

 Yes. Drop it straight into the stored water.

Will the water taste of chlorine?
 Not at the correct dose. A strong chlorine smell almost always means an overdose which a measured tablet prevents.

 No. Chlorine disinfects; it kills bacteria. It does not reduce hardness, dissolved solids, or metal content. For those you need filtration.
