CL2 can also get eaten up if lot of nitrogen (from debris, pee, sunscreen, sweat). It is best to test CL2 and pH levels all the time as they change daily depends on pool usage.
High alkaline water leads to high pH. Low alkaline water leads to low pH. Keeping your pH levels w/in proper range is important for keeping your equipment and pool finish intact. Your chlorine will dissolve quicker with a low pH level. High pH levels make chlorine inactive.
