When You Should Shock Your Pool?

via: poolstar.net

When you are chlorinating a pool, it is very easy to determine when a shock treatment is required. You can use a test kit which can include both free and total chlorine. Free chlorine is what is available to kill bacteria; total chlorine is the addition of free chlorine and what has been used for dissolving organics.

You should shock if the level of total chlorine is more than the amount of free chlorine.Have you ever visited a public pool and you were put off by the chlorine smell? I know it might surprise you to learn that it might have been caused by less chlorine rather than too much of it.

When the level of organics is too much, the smell is the by-product. That is a combination of chlorine, chloramines, and ammonia.

A shock treatment should be done to get rid of the organics. This should be followed by an addition of chlorine daily to prevent build up in the future. You might also want to shock after heavy use, after a water change or after a heavy rain or windstorm which might have blown debris into the pool.
