Choosing the Right Chlorine Granules

Understand the Different Types of Chlorine: There are several types of chlorine available in the market such as calcium hypochlorite, sodium hypochlorite, and dichlor. Each of these types has its own unique characteristics that make them suitable for different pool types.

Consider the Stabilizer Level: Stabilizer (cyanuric acid) is added to prevent the chlorine from breaking down under sunlight. If your pool already has a high level of stabilizer, then it’s better to choose a chlorine product with lower stabilizer content.

Check the Chlorine Content: Chlorine granules are available in varying strengths. The most commonly available chlorine granules come in 65% and 70% strength. Choose the one that is most suitable for your pool based on its size and needs.

Decide Between Quick-Dissolving or Slow-Dissolving Granules: Quick-dissolving granules are great for shocking the pool and raising the chlorine levels quickly. However, they tend to be more expensive than slow-dissolving granules that release chlorine over a longer period of time.

Look for Additional Features: Some chlorine granules come with additional features such as algaecide or clarifier that can help keep your pool clear and free of algae. Consider these additional features when choosing the right chlorine granules for your pool.

Different Types of Chlorine Granules

Calcium Hypochlorite: This type of chlorine granule is the most common and effective form of granular chlorine. It has a high concentration of available chlorine and is generally less expensive than other types of granules.

Lithium Hypochlorite: This type of chlorine granule is more expensive but dissolves more quickly than calcium hypochlorite. It’s ideal for vinyl-lined pools, as it won’t cause staining or bleaching.

Sodium Dichlor: This type of chlorine granule dissolves quickly and doesn’t require pre-dissolving. It’s a stabilized form of chlorine, which means it contains a small amount of cyanuric acid, making it ideal for outdoor pools exposed to sunlight.

Potassium Peroxymonosulfate: This type of chlorine granule is a non-chlorine oxidizer and is used to shock the pool, remove organic contaminants, and eliminate chloramines. It’s effective at eliminating bacteria and algae without increasing chlorine levels.

Trichlor: This type of chlorine granule is stabilized, slow-dissolving, and often used in a chlorine floater. It’s ideal for outdoor pools and hot tubs because it contains cyanuric acid, which helps to protect the chlorine from being destroyed by UV rays.

Calculating the Right Amount of Chlorine Granules

Step 1: Determine the size of your pool in gallons. You can usually find this information in your pool manual or by searching online for a pool volume calculator.

Step 2: Check the chlorine levels in your pool using a testing kit. The recommended chlorine level for a pool is between 1 and 3 parts per million (ppm).

Step 3: Determine how much chlorine you need to add by using a pool chemical calculator. These calculators take into account the size of your pool and current chlorine levels to give you the correct dosage of chlorine granules to add.

Step 4: Follow the instructions on the chlorine granule package to measure out the correct amount of chlorine granules. Always add the granules to water and not the other way around to avoid potentially dangerous chemical reactions.

By following these steps and taking the time to properly calculate the amount of chlorine granules needed for your pool, you can ensure that your pool stays clean and safe for you and your family to enjoy all season long.
