This investigation was done in response to a complaint received about a party of 6 people yesterday who were coughing when they were at the top of the slide. The materials used to clean the deck does not contain ammonia or chlorine. I used the Taylor test kit to see how much free chlorine and and total chlorine was in the pool. The free chlorine was 2ppm. The total chlorine was 5ppm. The combine chlorine is total chlorine minus free chlorine 5ppm- 2 ppm = 3 ppm. I will call the person who complained to follow up .
