picked up test kit and 24 gallons of 12.5% liqiud cl
just added 3 gallons and we have brown! - its working!
I am getting ready to dive into the test kit instructions so I can test accuratally, looks a little overwhelming at first but I am sure I'll get the hang of it.
Anybody else who has gone through this in the past, please chime in with any tips or suggestions.

Thanks again!
