This was brought up in another thread and I thought I would ask it here since I am the curious type. I did a search and didn't find the answer.
The jug of bleach that I use lists the % as 8.25, but under the ingredients list is an asterisk that states that the available chlorine is 7.85%. I have been using that number in the calculator to figure out how much CL to add to hit my target level. Is this correct or should I be using the 8.25%, and the calculator is already compensating for the lower yield?
