Keeping your swimming pool water clean and sanitary is one of the most important steps for pool maintenance. Let In The Swim’s 3 inch chlorine tablets for pools help. With a powerful active ingredient and slow dissolving formula, our chlorine tablets will keep your swimming pool water sanitary longer, saving you time and money.
Chlorine tablets contain 99% Trichloro-S-Triazinetrione (Trichlor) and 90% available chlorine, making it one of the strongest products on the market. Each 3 inch chlorine tablet is sun-stabilized which increases longevity in outdoor swimming pools.
Pool chlorine tablets help you avoid inconsistent chlorination, which is a common occurrence when using granular or liquid chlorine to sanitize a pool. Keeping your pH and alkalinity levels balanced helps with the effectiveness of pool chlorine in the water.
Our chlorine tablets for pools are 3 inch in size, individually wrapped in easy-open bags, and work great in chlorine floaters and automatic chlorine feeders.
With more than 40 years of experience making and selling chlorine tablets for above ground pools, in-ground pools, spas, and hot tubs, In The Swim is THE brand you can trust for clear, clean, and safe water.
