In The Swim 1 in Stabilized Chlorine Tablets - Fast Dissolving Pool

Our review of these 1 in stabilized chlorine tablets finds them best suited to pool owners who want a reliable, highstrength sanitizer that fits floating feeders and automatic chlorinators. The bottom line: the tablets deliver a high available chlorine content that keeps water clear and helps prevent algae, making them a practical choice for regular maintenance. While dissolution reports vary among users, the product's consistent chlorine concentration and compact 1 in size make dosing simpler and reduce uneven chlorination compared with larger tablets.

Key Features

• Powerful sanitizer: With 90% available stabilized chlorine and a high percentage of Trichloro-S-Triazinetrione, these tablets rapidly reduce bacteria and organic contaminants in pool water.
• Balanced dosing size: The 1 in tablets are small enough to help avoid inconsistent chlorination and make it easier to control chlorine levels from feeders or automatic chlorinators.
• Designed for feeders: Tablets dissolve at a faster rate when used in floating feeders and automatic chlorinators, helping maintain a steady residual.
• Versatile application: Suitable for hot tubs, spas, above ground and in-ground pools, so a single product covers most backyard setups.
• Individual tablet weight: Each tablet weighs approximately 0.5 ounces, which aids predictable dosing by count rather than guesswork.

Who It's For

This product is aimed at homeowners and maintenance professionals who prefer a stabilized, highstrength chlorine tablet for routine sanitizing. It is particularly useful for those using floating dispensers or automated chlorinators where a consistent dissolution rate and tablet size matter.

Those who should look elsewhere include pool owners who require non-stabilized chlorine, granular shock treatments, or very slow-dissolving formats for specialized feeders. If you need instant shock-level sanitation, a dedicated shock product would be a better fit than daily-use tablets.

Pros & Cons

Pros

• High available chlorine content provides strong sanitizing power and effective algae prevention.
• Compact 1 in size helps achieve more consistent chlorination and easier dosing control.
• Works well in floating feeders and automatic chlorinators, with many users reporting good dissolution in those devices.
• Good value for pool owners needing a standard, routine sanitizer for various pool types.

Cons

• Customers report mixed dissolution rates; some find tablets slower to dissolve outside of feeders or in cold water.
• Stabilized formulation may not be appropriate when non-stabilized chlorine is specifically required for certain treatments.

Specifications
