Okay, I checked my pool tonight and have the kit shown below which said I was high on both counts . I dumped it before I took the pic, but it was high on both sides. So I want the chlorine to be high to get rid of my algae problem ( water is crystal clear) but I need to get my pH level down. What am I to do/use to bring that level down?
