My question involves the regulations and the short-term health effects of swimming in water that contains too much chlorine. The other night, our pool (indoors) measured as follows:
pH: 6.8 - 7.0
Chlorine: 10 ppm
My understanding is that the pH should be in the 7.2 - 7.8 range, and the chlorine should be in the range of 1 ppm - 3 ppm.
My questions are:
1. Is there a safe upper limit for chlorine in a pool?
2. If the pool tests above that limit, should it be closed?
3. What are the short-term health effects of swimming in water
chlorinated to 10 ppm?
Some brief research on my part so far has only shown that our county has an acceptable mininum level (1 ppm), but no guidelines on a maximum level.
