What Are Essential Pool Chemicals?

Keeping your swimming pool clean and healthy is essential. Such care is necessary year round to ensure that the water stays sparkling. In order to keep your swimming pool at its best you need to use chemicals. Knowing which chemicals to use and how to use them will make the job much easier. Adding chemicals is pretty easy once you understand the essentials.

There are various types of chemicals for swimming pools that can be used for different reasons. The most common of these chemicals is chlorine. Chlorine is a staple that is necessary for all pools. Chlorine provides a way to have crystal clear water that is free from germs and growth. It also inhibits the growth of bacteria by killing it.

Chlorine alone isn't always enough to keep the pool sparkling clean. Many forms of bacteria and algae are resistant to chlorine in small amounts. If you add too much of it the water becomes inhabitable for swimming. So there are other chemicals that can be used in conjunction with chlorine to keep the water clean and fresh.

The way to keep the water clear and clean is to ensure that there is a proper balance in the pH of the water. To do this you must periodically test the water. A test kit is necessary to know what type of pool chemicals are needed. The pH of the water depends on many factors. The most important factor is the water that is originally added to fill the pool.

Water with high calcium levels tends to get a chalky deposit along the water line. Water that is too low in calcium can be increased by adding special calcium hardness increaser while water that is too high in calcium should also be treated. Pool shock is a special type of chemical mix that is added to the water to quickly restore the proper pH and create clear water for swimming.

Stabilizer is another important chemical. Stabilizer is also commonly called cyanuric acid. Testing for stabilizer is usually done at the beginning of the season. Once the stabilizer is added it should maintain in the water for the summer. Stabilizer helps chlorine do its job. If there is too much or too little stabilizer in the water you may find that your chlorine is not working properly. If this is the case you should retest for stabilizer and add more if needed. When you need to reduce the stabilizer in the water the only efficient way to do so is to partially drain the pool of water and refill.

If the water has started to have algae you will need to use an algaecide. This helps to eliminate the growth of algae to keep your water looking crystal clear. There are two main types of algaecides on the market. The most common is a copper based algaecide that uses copper to effectively kill algae. The drawback with using copper based algaecide is that it can stain if improperly used. Quat or polyquat algaecides will also kill algae but will not stain. These algaecides can cause foaming, however.

If your pool water takes on a cloudy appearance you may need to use a clarifier. Clarifiers work to help clump tiny particles together so that they are more effectively cleared out by the filter. Enzymes can be used to help break down particles and debris in the pool so that the chlorine is more effective. Using enzymes in the pool can help to reduce the amount of strong chlorine that is needed to keep your water sparkling.
