Rx Clear 1 in Chlorine Tabs 100 lb - Slow Dissolve Sanitizer

In this review the Rx Clear 1 in chlorine tabs are evaluated as a straightforward, heavy-duty option for pool and spa owners who want reliable sanitization without strong odors. The bottom line: this 100 lb, two-bucket pack is best for people who need a long-lasting, stabilized chlorine source that maintains consistent chlorine levels and prevents algae and bacteria. Reviewers and hands-on users will appreciate that the tablets are UV stabilized and formulated to minimize skin irritation while keeping water crystal clear.

Key Features

• High available chlorine: Composed of about 90% available chlorine, the tabs provide powerful sanitization while keeping odor and skin irritation lower than some alternatives.
• Slow dissolving: The tablets dissolve slowly enough to be safe in floaters, dispensers, and automatic feeders, reducing the need for constant refilling.
• UV stabilized: UV protection helps preserve the tablet effectiveness and protects vinyl liners and surfaces from premature fading.
• Family and pet friendly: Formulated to maintain steady chlorine levels that help prevent harmful bacteria while being suitable for pools used by pets and children.
• Versatile compatibility: Safe to use in pools, spas, hot tubs and on common surfaces including vinyl, tile, fiberglass, and gunite.

Who It's For

This product is aimed at homeowners, pool service pros, and hot tub owners who prefer a stabilized, long-lasting chlorine source and who want a bulk supply to reduce shopping frequency. It suits larger pools or properties that cycle a lot of water and need a predictable sanitizer that integrates with floaters, in-line feeders, and automatic dispensers.

Those who should look elsewhere include owners who need unstabilized chlorine for certain shock treatments or very small systems where tablet size and dissolution variability are problematic. If you require quick, high-concentration shock dosing, a different product dedicated to shocking is a better choice.

Pros & Cons

Pros

• High available chlorine content provides robust sanitization and algae control.
• Slow dissolving formula works well in floaters and automatic feeders, reducing maintenance.
• UV stabilization helps protect pool liners and preserves tablet potency in sunlight.
• Good value for bulk buyers needing 100 lb of supply split across two buckets.

Cons

• Some users report mixed dissolution rates, with a few finding tablets dissolve faster than expected in very warm water.
• Bulk weight and storage volume require adequate, dry storage space and careful handling.

Specifications
