Pool company keeps our pool at about 60 – 80 ppm TA and pH at 7.8 – 8.0+. How does this impact chlorine consumption versus a TA at 80 – 120 and the pH at say 7.4? Also, how effective is the chlorine with the pH at 8.0?Thank you!

Answer:

The pH is the more important factor in the chlorine chemistry. Chlorine is most effective at the low end of the ideal pH range of 7.2 to 7.4. However, it is still very effective and likely to be more comfortable for swimmers around the 7.8 level. At 8.0 it is starting to get a little too high as the upper end of the recommended level is 7.8. Either way the actual chlorine consumption should be very similar.
