I have been able following the recommendations here to get rid in less than a week of a beginning of algae growing in my pool. The water is now Crystal clear, I will see if the FC is going down during the night but for the last two days the water is visually clearly better.
I have run my test:
------------------------------------------
Test Results 07-13-2020 @ 08:35 PM
------------------------------------------
Free Chlorine: 14.0
Combined Chlorine: 0.0
pH: 7.8
Total Alkalinity: 80
Calcium Hardness: 70
CYA: 55
Temperature: 29°C
CSI: -0.48
I believe it is safe to swim in the pool as the FC is below the slam level for this quantity of CYA. Would you suggest me also to lower the CYA by removing and adding water ? I was at 50 and I have used last week to small bag of shock that could have increased my CYA I presume.
Thanks for your help, again and again. !
