Answer:

Typically yes. The chlorine odor comes from chlorine that has combined with wastes in the water and formed "combined chlorine." This form of chlorine is unwanted in the swimming pool and when it builds up so does the odor and skin and eye irritation that comes along with it. It may be an indicator of a lack of the good kind of chlorine (known as free available chlorine) present in the water. The saying in the industry goes . . . "if you can smell the chlorine, you need to add more chlorine." By adding more chlorine it will oxidize the combined chlorine and get rid of it from the pool.
