How to Shock your Swimming Pool
Think of all the dead skin cells, body oils, sweat and cosmetics - not to mention urine - that may be lurking in your pool. Shocked? You should be! "Shocking" a pool refers to using a chemical process called oxidization to break down water-soluble bather waste.
1. Purchase pool-shock products from your local swimming pool dealership. Choose products according to the type of filter system you have. ("Shocker" is known by several names: oxidizer and burner are a couple of the more common ones.) Use the shocker that is suited to your pool system - non-chlorinated for non-chlorinated pools and chlorinated for chlorinated pools.
2. Use the proper amount of the shocker by reading the manufacturer's specifications. How much you use depends on the size of your pool. Most brands come in a quick-dissolving powder that is broadcast in the deep end of the pool.
3. Use your pool skimmer to help mix and distribute the shocker treatment and speed the oxidization process.
Bather waste, combined with chlorine, can cause a strong chlorine-type odor and cloudy water that irritates eyes and skin. Breaking these inevitable and natural waste products down makes it easier for them to be removed from the pool and puts less stress on equipment like filters and pumps.
