Thanks I looked it up and the level is fine. Still have cloudy pool. Super shocked it Monday evening after I vacuumed to waste bottom was pretty dirty. I put in 9 bottles of shock and after about 3 hours I took a reading with the Taylor 2006 kit. Reading are FC - 19
CC - .5
TA - 170
CH - 250
PH - 7.2
CYA - 45
since then I been keeping up with the shock. This morning Still at shock level. Still seems to be no improvement. IS there something I'm doing wrong.? Filter running 24/7 back washed once which was yesterday. Is there something else I could try. Seems like there's alot of stuff floating in the water. When I vacuumed on Monday - Alot of white and brown slimey stuff in the strainer. Thanks for your help!!!!
