Get chlorine in the pool. Add 10 ppm worth of CYA at a time. Target 30 ppm CYA. Use SLAM level FC of 12 ppm.
I added liquid cya 24 hours ago. I had done the math wrong for 10pm and accidentally added enough for an additional 15ppm
Just did a test and I can still see the dot filled to 30. Should I wait awhile before adding another 10pm?
