Every pool owner knows that you have to shock your pool from time to time. But after you do, how long do you have to wait before it is safe to swim again? Here are a few things you need to know.
Chlorine and other shock materials are effective ways to keep your pool clean and safe, but over time, it can lose its efficacy. This is why pools require “shocking” every so often — the process of adding a large amount of chlorine all at once in order to disinfect the water and kill any algae or bacteria. Shocking also helps to remove any unpleasant chloramines that may have built up in the water.
But after you shock your pool, how long do you have to wait until it is safe to swim again?
The general rule of thumb is that you should wait at 8 hours after you do the shock in order for the chlorine or other materials to disperse. However, it is always best to check with your local pool supply store, shock manufacturer, or service provider for specific guidelines. Some manufacturers say 6, some experts say 12, so make sure to read the instructions.
Make sure you do the shock in the evening, when the sun is down because it can lower the effectiveness of the shock. Also, make sure the pump is running so you get good distribution within the pool!
Even better than waiting is to test the chlorine levels and make sure they are safe and even comfortable for swimming before you jump in.
Pool Shock Thoughts
Shocking your pool is an important part of keeping it clean and safe, but it’s important to know when it is safe to swim again. Use the general rule of thumb (waiting 8 hours) as a starting point, but always check with your local pool supply store or service provider for specific guidelines before getting back in the water.
