After you put on bottle of chlorine in your pool. how long until can go swimming?

It is generally recommended to wait at least 30 minutes after adding chlorine to a pool before swimming. Chlorine is a disinfectant that kills bacteria and other microorganisms that can cause illness, and it needs time to work. The amount of time you should wait can vary depending on the specific chlorine product you are using, so always read and follow the manufacturer's instructions. Some products may require more or less time to become fully effective.

In general, it is better to err on the side of caution and wait a little longer than the minimum recommended time before swimming. The higher the chlorine concentration in the pool water, the shorter the waiting time may be. However, keep in mind that swimming in water with high levels of chlorine can also irritate your skin and eyes.

Also, remember to shower before swimming to remove any dirt, sunscreen, or other contaminants from your body that could react with the chlorine and create unpleasant compounds.
