My TA is currently at 70. My ph is about 7.6. What is the the ideal TA for a manually chlorinated pool? Tfp says 60-90 but my test kit says 100-120. My daughter is complaining of her nose and eyes itching in the pool and she thinks it’s the chlorine level which is kept between 7 and 10. My cya is 60. I’m not sure which is the issue. The water looks great!
