Some home remedies for your pool can also be used along with chemicals. Baking soda, borax and plants are three things you can use as home remedies for pool chemicals.

You can prepare substitute pool chemicals at home.

Baking Soda

Baking soda or sodium bicarbonate is an Alkalinity Increaser and can be used as a home remedy for pool chemicals. Baking soda will raise the total alkalinity, or the minerals in your pool water that buffer pH or acidity. It's best to use baking soda only if the total alkalinity in your pool needs raised a little. The large granules in baking soda will make the pool water cloudy if to much is used. Make sure you use baking soda and not soda ash if you only want the total alkalinity raised. These are two different products.

Borax

Borax is a natural substance known as sodium borate or sodium tetraborate. It's environmentally friendly and can be used as a home remedy for pool chemicals. It raises pH levels and total alkalinity. It's recommended to add Borax very slowly to your pool and to check the pH levels and chlorine levels before each use. Begin with a cup if your pool is small and 2 cups if your pool is big. PH levels will rise when borax is first added, so check again in 24 hours. Borax or sodium tetraborate should be the only ingredient in the box.

Plants

Plants can be used as a home remedy for pool chemicals to help keep your pool clean. The pool is separated by a low wall. One part is used for swimming and the other part is used to put the plants, which is called the regeneration zone. A pump is used to circulate the water between the two areas. Return lines, a main drain and skimmers are often used so pool chemicals aren't needed. You can use a variety of plants that will absorb bacteria and pollutants into their root systems. It's important to take care of the plants to make a natural pool work the way it's suppost to.
