Great job on testing.
Get 30 ppm worth of CYA dissolving using the sock method.
I would not touch pH right now. Just start the SLAM Process.
Once you get the CYA dissolving, add liquid chlorine to get to 12 ppm FC and maintain it there several times per day.
From now on, use a 10ml sample for FC testing. One scoop of powder, each drop of reagent to clear is 0.5 ppm FC.
Just test FC during the SLAM.
