New to the forum just realized how much the pool place has been ripping us off! Testing kit ordered so I don't have to deal with them anymore. So here are the numbers from the first sample I brought to the pool place
Total Chlorine: 0.7
Free Chlorine: 0.2
PH 7.6
TA 129 (adjusted total alkalinity:86)
CH 69
CYA 143
So I followed the pool places recommendations and added 22.5lbs of baking soda (they said balance pak 100 but I learned my stuff on here), then added 2.25 lbs of Lo N Slo. Then two bags of burn out 35 to bring up chlorine residual. Water was still cloudy so started researching more on here and figured out CYA was too high. So I drained the pool 6 inches (I know I need to do more one of the posts I read to do it in stages. So after the partial drain and refill I took it back in and here are the new numbers:
Total Chlorine 2.2
Free Chlorine 0.5
TA 173 (adj. total alk 128)
CH 87
CYA 151
Why did the CYA go up? Was it the burnout I used before I drained. I know it wasn't going to bring the number all the way down to 50 but why did it go up?
