I am attempting to do the OCLT
Has anyone noticed that not all the bleach has the strength noted on the bottle
Since I did NOT buy it from the dollar store,ect..... I used 6% in the pool calculator
After adding the proper amount of bleach(4 gals),my FC only went from 10 to 15
I am thinking they were 3%
How can they get away with not listing the strength
Any suggestions on where I can find the 12%?
