Having issues measuring our CDS to achieve 3,000 ppm.

I'm having trouble measuring our CDS. Making my own. Clip jar, shot glass method. I did it in two stages over 2 days, as suggested by Andreas and diluted a 1 ml sample in 9 ml of Evian water and the 500 pm test trips came out brown medium? Then I diluted the amount in water, perhaps too much. Now no matter what way I test this by diluting down samples in various ways the test strips always seem to come out light-medium teal colour. I'm finding this whole things surprisingly confusing.

Can anyone help me figure this out? Thanks.

You might want to try making CDH4000 instead. Then you can throw away your test strips because if you just follow the directions you'll end up with 4000 ppm. This is one of the reasons I prefer CDH over CDS:



Take care,

If you follow my method as shown by AK, you will get pure, 3000 ppm, CLO2 in water, aka CDS.

1. You are referring to clip-jar shot glass method, yes?

2. What do you recommend regarding proportions? 5 ml of each in shot glass? (.25 + .04)

3. How many ml of water?

4. Do this two times to double the CDS concentration?

5. Over how many days?

6. Store in cupboard or fringe for making the CDS?

@Scott

Thanks for the tip. For now though I believe I will stick with CDS for its purity.

Okay

1. You are referring to clip-jar shot glass method, yes? Yes

2. What do you recommend regarding proportions? 5 ml of each in shot glass? (.25 + .04) 5ml of MMS and 5ml of 4% HCL in the shot glass.

3. How many ml of water? 240ml

4. Do this two times to double the CDS concentration? See my 2015 PDF for details.

5. Over how many days? Usually 2 overnight activations.

6. Store in cupboard or fringe for making the CDS? You can make this CDS at room temp or in a fridge. Best to store in a fridge.

@CLO2

Thanks.

Make in cupboard, then store final product in fridge?

I say this because when I tried to make some yesterday in the fridge some of the stuff in the shot glass was separated by the next day and I think I lost some concentration by trying to make it up in the low temp of the fridge (3ºC)

"Make in cupboard, then store final product in fridge?" Yes.
