Color of Chlorine

[joe111]

good day everyone.

I hope everyone is doing well.

Just a quick question. whats is the color of pool chlorine? A dark yellow? Where as home bleach is a lighter yellow?

Can anyone take a photo of the chlorine they currently have in a jug?

I am asking because I thought pool chlorine was a darker yellow and very strong smell. the liquid chlorine i just purchased it watery and little to no smell.

please and thank you

Where did you buy your chlorine?

What was the date code on the bottle or case?

I purchased from our local pool store. Just a refill 20 liter jug no date stamps

The yellow comes from a bit of iron in the production process and isn't a worry. I've never seen dark yellow chlorine??

so i bought chlorine from another store and it was a much darker yellow. So either the the first pool store was selling old stock or watered down or something else wrong.

so I am not crazy

Check the date code, and after you add the new stuff check to see if it got you the FC you desired? About an half hour after adding and letting the pump mix it in.

You run a test to verify your bleach strength: When you dilute the bleach in a ratio of 1 : 10000 with water that contains no chlorine, then the bleach percentage will show in ppm as FC.

E.g. 1 gallon of 12.5% liquid chlorine added to 10000 gallons of water will increase FC by 12.5ppm.

On a smaller scale, you can add 10ml of your bleach (with a syringe) to 1 litre of distilled water. Mix well and take 10ml of this mixture and add to another litre of distilled water. Mix well and test FC on that.

Or 1ml of bleach diluted twice with 100ml distilled water. Probably still sufficiently precise for this purpose (especially if you have a 1ml syringe), and a more reasonable amount of distilled water.
