In The Swim 1 in Stabilized Chlorine Tablets - Fast Dissolving

In this review the In The Swim 1 in Stabilized Chlorine Tablets are assessed for routine pool sanitizing, aimed at pool owners who want a straightforward, cost-effective way to keep water clear. The bottom line: these Tri-Chlor tablets deliver a high 90% available stabilized chlorine concentration that reliably eliminates bacteria and helps prevent algae, making them a solid choice for hot tubs, spas, above ground and in-ground pools that use floating feeders or automatic chlorinators. They are best for users seeking consistent sanitization from small 1 in tablets that dissolve faster than larger formats.

Key Features

• High available chlorine: With 90% available stabilized chlorine the tablets provide strong sanitizing power to control bacteria and algae effectively.
• Tri-Chlor formulation: The 98.6% Trichloro-S-Triazinetrione base delivers stabilized chlorine that resists breakdown from sunlight, extending residual protection.
• 1 in tablet size: Smaller 1 in tablets help avoid uneven chlorination and are easier to use in floating feeders and automatic chlorinators.
• Faster dissolving in feeders: The size and formulation allow tablets to dissolve at a quicker rate in floating dispensers and automatic systems for steadier chlorine delivery.
• Compact tablet weight: Each tablet weighs approximately 0.5 ounces, so dosage is predictable for routine maintenance schedules.

Who It's For

These chlorine tablets are designed for pool owners who run regular sanitizing routines and use floating feeders or automatic chlorinators. They suit those who prefer a stabilized Tri-Chlor product that offers strong, lasting chlorine levels without frequent shock treatments.

Users who need rapid shock-level sanitization or who prefer non-stabilized chlorine alternatives should look elsewhere, as this stabilized Tri-Chlor product is intended for ongoing maintenance rather than emergency or high-oxidation treatments.

Pros & Cons

Pros

• High concentration provides robust sanitizing and algae prevention.
• Small 1 in tablets give more consistent dosing in feeders and automatic chlorinators.
