I can't believe that my level is 0. Where is the chlorine going???!!!

Added a gallon of bleach this morning, and will monitor it today.

Water is murky, pea green color.

I know you all talked about goop on the filter, but mine was just a gold color with no goop. I was glad, since on Baquacil my filter would clog in a few hours. But, does this mean not enough reaction is happening?
