Here are the results of my first test. Its not pretty.
Fc/Cc no reading as I put 35 drops and it never changes color.
CL 5+ (orange color)
My pool usually takes about 1 cup of muriatic acid a week, I added last Sunday. At that time I slammed the pool with old 12.5% liquid chlorine 4 gal worth. I added more chlorine on Wednesday.
From the results I guess I have to change the water. I will pump half out today and then test tomorrow..
