My 2 sons and I jumped into the pool immediately after working out in the backyard. At first everything was fine, but after a few minutes we noticed a foul smell, like something was rotten or spoiled.

I checked the pool chlorine and pH afterwards. The pH was around 7.8 and the Chlorine was at 0.0ppm (Ooops!). I quickly added 3 (1.5gal) jugs of liquid chlorine. Each jug usually raises my chlorine by 6ppm. I keep the chlorine usually between 8-15ppm because my stabilizer is high, 180 - 200, from using those hockey pucks for so many years.

What caused the smell? Was there any danger? Was it just our sweat reacting with the pool water? But, without any chlorine, what was out sweat reacting with?
