Whether you shock your pool every week or do it once per month, a standard practice is to distribute dissolved chlorine tablets into the water so it can remove pollutants. Bacteria and organic pollutants will build up enough over time that they can actually resist your chemical balance. By shocking the pool, you can break up the contaminants to prevent a messy build-up of scum, algae, and other icky stuff.

You need to shock a pool because every time you step into one, you’re actually adding contaminants to the water. It’s something you just can’t prevent. Your skin distributes cells into the water and those cells can become food for bacteria and algae. Add in the leaves, dirt, and other natural stuff that Mother Nature can put into your pool and it becomes a fantastic place for bacteria to raise a family.


You basically need a 5-gallon bucket and your preferred shock chemicals for your above ground pool. Fill up the bucket with pool water and then dissolve the chemicals into it. Then pour one-quarter of the chemical solution into each corner of the pool. That’s really all you need to do.

It’s often better to shock a pool at night. The chlorine breaks down under the rays of the sun and can make the shock less effective. You also need to run your pumps for 8-12 hours on most pools for the shock to be effective, so you can run it all night and then be ready to use the pool again in the morning.

Check your chlorine levels at least once per week to determine what your current levels happen to be. If they are too low, then use the pool shock to restore your balance.
