How long doest take bleach to deplete when used in a hot tub?

Bleach can deplete relatively quickly in a hot tub due to factors like temperature, chlorine demand, and exposure to sunlight. Typically, the active chlorine in bleach can diminish within a few hours, especially in warmer water conditions. Regular testing of water chemistry is essential to maintain safe levels, as factors like bather load and organic matter can further accelerate depletion. It's advisable to add bleach as needed based on test results rather than relying on a fixed schedule.
