okay, i dont get it. all my numbers are correct according to the pool store. (dont have any current numbers right now) except for the fact that i'm not holding chlorine! no matter what i do its not working. i've been dumping bleach in as much as i can. i have my chlorinator on max 5. i have a floater filled with tablets. doesnt matter, the chlorine constantly tests at 0. the pool store said there is no chemical reason for it. they think i may have water mold. okay but how do i kill that?? its even brand new water and sand this year. not sure how i could have water mold from brand new city water. this is the most frustrating year since we put the pool in!!
