What Chemicals Are Necessary for Closing a Pool?

Swimming pool closing isn’t a complicated task if you have the right tools. There are a variety of chemicals you need to use to close your swimming pool to prevent many different problems. Why is winterizing your swimming pool so important?  Keep in mind that the water is stagnant throughout the winter. Your water isn’t being circulated or filtered. The pool also isn’t being sanitized. Your pool becomes a perfect environment for algae to grow.

The chemicals serve a variety of purposes. First, they protect the pool from freezing weather. Next, the chemicals will help prevent the growth of algae which can become a serious problem. Good winterizing protects your pool equipment which is costly to replace. Finally, treating the water with the appropriate chemicals will make it easier for you to open the pool the following spring.

There are several swimming pool chemicals that you will need. Check the pH of the pool. If it is not in the appropriate range, add soda ash to the water to adjust the pH. You should check the alkalinity level and use an alkalinity increasing product to ensure that the water is in the right range. Always add a chlorine-based shock product which will dissolve quickly and clear the swimming pool of impurities.

Always add an algae control product to the water before covering it for the season. This is often referred to as a winterizer. These products are designed to kill and prevent algae throughout the entire winter season. A stain prevention product is important. It can prevent costly liner strains from building up due to metals and other minerals. The last thing you want to do in the spring is deal with a waterline buildup. All these chemicals work in conjunction with your winter pool cover to help you keep your pool in good condition even if there is a warm spring before you open your pool.

The Relationship Between pH Balance and Alkalinity

Swimming pool chemical balance is critical to maintaining clean and safe water. It’s important to test your water regularly to ensure that it is balanced. Sometimes, chemical balance can be tricky. Chlorine isn’t the only part of balancing water. There are several other factors involved in balancing swimming pool and one of the most critical issues is the pH balance of the water. The pH of the water affects how well the pool sanitizer, such as chlorine, works.

swimmerDid you know that there is a significant relationship between pH and alkalinity? When the pH is out of balance, it affects the pool alkalinity. You can’t adjust the pH of the water effectively unless the alkalinity is in balance. Most experts recommend that the pH of swimming pool water is between 7.2 and 7.6 for the pool chlorine to work properly. High pH can cause a calcium buildup, filter clogging, dull water and a variety of other problems. If the pH is too high, you need to check the total alkalinity of the swimming pool water.

The total alkalinity of the water should be between 80 and 200 ppm. If the pH is high and the alkalinity is in the right parameters, you should add pH reducer. If the pH is low in the swimming pool water, you should check the alkalinity just like when the pH is too high. If the alkalinity is normal, then you should add a pH increaser to the water.

What if the alkalinity in the water is not balanced? High total alkalinity, the pH of the water will consistently rise even if you add pH reducer. To fix the problem, you need to adjust the alkalinity without affecting the pH balance. If the alkalinity is too low, add sodium bicarbonate which will raise the alkalinity without affecting the pH of the swimming pool water. What if the alkalinity too high? You should add a pH reducer to the deep end of the pool. You’ll need to shut off the pump and give the pH reducer time to lower the alkalinity and then you can turn the swimming pool pump on again.

Testing Water: What to Look For

Why is it so important to test your water? You need to ensure the health and safety of your swimmers. Sanitizers keep the swimming pool clear of contaminants. Without the right chemical balance, algae can grow quickly. Improperly treated water can increase the risk of infections or illnesses. When swimming pool chemicals are out of the appropriate range, they can cause problems with your equipment including the pump, pipes, filter and heater. Imbalanced swimming pool water can cause corrosion and ultimately lead to expensive repairs.

You should always test the water before you add chemicals. When you add chemicals to the water, it may take up to 24 hours for the water to adjust. Keep this in mind before you retest.

Water testing methods come in a variety of styles. You can purchase testing kits that use vials of water to test for different chemicals. Testing strips have become popular in recent years. You can also purchase electronic testing kits but these tend to be quite a bit more expensive.

If you decide to test swimming pool water using testing strips, always buy new strips each year. The strips lose their effectiveness over time. Keep any type of testing kit out of the sun and protect it from water so that you can get accurate results. Always test the water about one foot to one and a half feet below the surface.

What should you look for? If your chlorine levels are high, it can affect the results of the total alkalinity and pH in the pool. Check the cyanuric acid levels. It protects the chlorine from the sun, but if the levels are too high, the chlorine will become completely ineffective at sanitizing the swimming pool.

The pH level of the pool is just as important as the chlorine level. You’ll often find that the pH level of the water is high and you’ll need to lower it using muriatic acid or granular acid. If the pH level is continuously high, check the alkalinity which is probably low. Once you adjust the alkalinity, your pH level should be in the appropriate range.
