Types of Pool Chlorine Tablets

Choosing the right pool chlorine tablet is crucial for effective sanitation. Here, you’ll find details on the main types available.

Trichloroisocyanuric Acid (TCCA)

TCCA is a popular choice for pool owners. It contains about 90% available chlorine, making it highly effective for killing bacteria and algae. TCCA tablets dissolve slowly, which helps maintain steady chlorine levels over time. Use TCCA for regular sanitizing; it’s especially useful for outdoor pools with consistent exposure to sunlight.

Dichloroisocyanuric Acid (DCCA)

DCCA tablets typically contain 56-62% available chlorine. They dissolve more quickly than TCCA, making them ideal for a quick chlorine boost. DCCA is a great option for indoor pools or spas, where you might not need prolonged chlorination. Its fast-acting formula works well for shock treatments and regular dose adjustments.

Calcium Hypochlorite

Calcium Hypochlorite, often referred to as Cal Hypo, contains about 65% chlorine. It’s a powerful choice for shocking pools, particularly after heavy use or after rainfall. Cal Hypo tablets can raise the calcium levels in your water, which can be beneficial but may require monitoring to prevent scaling. Use Cal Hypo for initial sanitization or as part of your regular maintenance routine, ensuring you follow dosage instructions carefully.

Features and Benefits

Understanding the features and benefits of pool chlorine tablets helps you make informed choices for your pool maintenance.
