    Testing CYA

    I have a T-2005 kit that the PB supplied. When testing for CYA you add drops until the black dot disappears. My question is do you add drops until the black turns gray or until you can't see the dot. There is a big difference in the final reading.

    Perhaps this link from Taylor Technologies will help.

    Remember, this turbidity test is often referred to as the 'disappearing black dot test' not the 'greying black dot test'
