How do you get rid of chlorine when you put too much in your swimming pool?

Just wait it out, the Ch level will come down. When you add Ch (Shock) you are spiking the Ch level and normal conditions use Ch and lower the concentration. Unless you put so much in that it is having detrimental effects, you shouldn't worry. Be sure the Ph is in balance. If the Ph or Alkalinity is out of tolerence, you may have long term problems, like corrosion of tubing in the heater.

Good luck

There should not be a major problem unless the chlor level is above 10.0 ppm.
