  Anyone who has sensitive eyes can attest to how uncomfortable their eyes can be when they have been exposed to chlorine for an extended period of time. Pool owners have options to reduce the amount of industrial chemicals they use. They can choose more natural products to keep their pools clean.
  
  

Salt Water Pool

• While it requires an initial investment of approximately $1,000, as of 2010, to install a salt chlorine generator, a saltwater system offers a number of benefits to the pool owner. Salt is still a chemical, but it is far easier on the environment than chlorine. The initial cost of the salt chlorine generator is eventually recouped because the salt used in it is considerably cheaper than the same amount of chlorine.
  
  

Ionization

• Ionic pool cleaners use copper and silver to kill bacterial and stop algae growth in pools. Water molecules are converted into ions after being infused with small amounts of the metals. These metals are introduced to your pool by placing cartridges into your pool filter or using a special device that floats in the water.
  
  

Plants

• Choosing the right plants can filter your pool water as well. Certain plants can enhance the oxygen level in backyard pools and prevent algae from growing in your pool by consuming the same nutrients that the algae would consume.
