I have a 16k in ground we just took off the copper ionizer and trying to get my chlorine up . I double shocked with Hy Cal and have been adding liquid chlorine, last night I added 4 bags of shock Hy Cal and this morning this is my reading.Emptying the pool isn’t a great option the city just imposed water restrictions and we are penalized heavily, and likely entering the next phase , it’s super dry here . I checked to see if there was anyone who filters water for the CYA but didn’t find anyone . Any suggestions on improving my Chlorine numbers?
