We have a very busy semi public pool. Full Southern exposure.
Approx 100,000 liters
I added 3000 grams 100% CYA May 6, did a reading about 10 days later and it was maybe 20 ppm.
Did a reading middle of June and as far as I could tell it was 0. So I added another 800 grams CYA.
Tested again yesterday and I still am maybe getting a 10 ppm reading.
Am I just inept at reading this or have I just not added enough.?
I am going through about 40 litres 12% chlorine a week, which is literally the same as last year.
Does that seem about right for this size of pool.? I don't want to overdo it because we went through that one year too, not fun.
Any suggestions, greatly appreciated.
