I have a pool chemistry extended investigation, and I need to conduct my own tests and experiments. I have created a model pool of my own with chlorine in it, and have changed it to 3000ppm then to 4000ppm then to 5000pm using salt. As i have increased to these different ppm's I have conducted a titration on each one testing the chlorine levels. I need to discuss how all of this affects the pools equilibrium. What sort of stuff can i include in this?
