Now that I have your attention, I am a new above ground pool owner thanks to COVID. Summer Waves 9' x 18' with Summer Waves filter, 5000 gallons. I was using ClearView Shimmer and Shock to manage the pool and all of sudden the CYA level reached 152. I drained the pool and now these are my levels from Leslie's I tried to use the pool math on my phone but was so confused by it! Any advice welcome!! I have been told to use liquid chlorine to avoid the CYA increasing.
Free Chlorine 0.4
Total Chlorine .56
ph 8
total alkalinity 42
Calcium hardness 15
CYA 19
iron 0.1
phosphates 299
