Testing cheap bleach

[CarlD]

I take a 10ml eyedropper of the LC, and drop it in 10 liters of water...5 2liter soda bottles...and measure it the way I would measure pool water.

Ok now I got what to use to test,,,,but are we saying AFTER I make the mixture THEN using my 2006 I test with the powder and go from there?

The idea is to dilute the LC in a water solution to mimic the pool. So adding 1 gallon of LC to 10,000 gallons in a pool is 1: 10,000.
I mis-wrote above..my eyedropper (glass) is 1 ml, not 10. So....1 ml of LC in 10 liters of water (five soda bottles full) is the same as 1 gallon in 10,000 gallons.

I mix it up in a 5 gallon bucket, then test it with my trusty FAS-DPD test. Whatever it reads is the concentration of the LC/bleach.

However, it's a good idea to test the water FIRST before you add the LC because public water frequently has an FC reading, and you'll want to subtract that.

Ok Carl never thought about deducting will do.
