Ok. I went to my friend's house to check her pool water. She turned on the tap water and the chlorine smell was unreal. I checked the chlorine levels of her tap water and these were the results:
I researched an acceptable level of chlorine for human water consumption and it maxed out at 4 ppm. When we called the water tech guy who maintains the levels, I was told by him, "The CC level is always high than the FC level."
Am I confused?
