There are two basic types of chlorine (chemical name “Cl”) available for swimming pools: liquid and granular. You’ll want to choose the one that works best for your pool and your budget. In addition to these two types, you’ll want to know the cost of Cl, what alternatives are available and how safe they are.
Liquid chlorine vs. granular chlorine
Liquid Cl is a fast and efficient way to sanitize your swimming pool. However, it can also lower your calcium and stabilizer levels. To avoid these problems, you should use granular Cl instead of liquid Cl for your swimming pool. This type of Cl is also lighter and easier to handle.
While both types of Cl have their advantages, the main difference between them is their cost. Liquid Cl is less expensive and is available in convenient refillable containers. It is also non-staining and leaves no residue after it has done its job. However, liquid Cl is more difficult to store and transport.
Another difference between the two forms of Cl is their pH level. Liquid Cl contains cyanuric acid, which makes it highly corrosive. In a smaller pool, this can cause problems. Liquid Cl can also leave high levels of cyanuric acid in the water, which will make the water cloudy and less effective.
Alternatives to chlorine
If you want to use chlorine alternatives to clean your swimming spot, there are several types of systems to choose from. These systems either use Cl separately or have built-in filters that produce chlorine automatically. Some are more effective than others, and some even reduce the amount of harmful chemicals used.
Among the most common pool Cl alternatives is an ionizer, which you can click here to learn about. Ionizers work by introducing metallic ions to the water using a low voltage current. The positively-charged ions attract and destroy the negatively-charged bacteria and algae.
Non-Cl shock treatments are another great alternative to chlorine. They can reduce your swimming spot’s need for Cl by 50 percent. These are cartridge-based systems composed of minerals that kill bacteria, algae and microorganisms. However, you will need to replace the mineral cartridges every few months. As a result, they add up to your swimming spot maintenance budget.
Cost of chlorine
Cl supplies have increased significantly in price since the supply shortage started two years ago. As a result, the chemicals you use are at a higher price point than ever before. Although some local stores will teach you how to use liquid chlorine, they have recovered and have stocks of Cl, the shortage still persists. This is bad news for owners as these trends typically go upward over time.
In some places, the shortage is so severe that some public pools may have to close. This is frustrating, but more Cl alternatives are appearing in the market. One of the most popular alternatives is bromine, which is close to Cl, but it is easier on your eyes and skin. Another option is to swim before you shower, since this will reduce the amount of oil and bacteria in the water.
If you’re worried about algae growth, you can also add a phosphate remover to the water. This will prevent algae growth and also help the water pH remain stable. The amount of Cl needed will vary depending on how much you swim and how often you use it. A 20,000-gallon pool needs about one ton of Cl per month.
Safety of chlorine
The safest levels of chlorine for a swimming pool are those that stay between one and three parts per million (ppm). Higher concentrations can make swimmers itch and their eyes turn red. The best way to determine your swimming spot’s Cl level is to test it regularly. If the level is too high, wait four hours before adding more.
When mixing chemicals in it, it is important to wear personal protective equipment. Inhaling the toxic gas from these chemicals can cause severe burns on the skin and eyes. Wearing a face mask and wearing gloves are essential. In addition, the area should be well-ventilated.
Cl is a chemical that can kill many germs in water. It has been used for decades to disinfect pools and water. It is also known to protect swimmers from athlete’s foot and swimmer’s ear. It can even remain effective long after it is applied. The CDC offers a poster describing the benefits of Cl for pools (www.cdc.gov/healthywater).
Cl is poisonous when it is not diluted. Although the safest amount of Cl for your pool is one part per million, there are still risks. Do not overuse Cl or mix it with any acidic product, as this can lead to explosions. When you add Cl to your pool, make sure you are careful to keep your children safe.
