Rx Clear 15 lbs Granular Pool Chlorine - Stabilized Dichlor for Clear

Our review of Rx Clear 15 lbs Granular Pool Chlorine finds it best suited to pool owners and hot tub keepers who want a straightforward, fast-dissolving sanitizer that preserves water clarity without aggressive chlorine harshness. The biggest reason to buy is the product's stabilized dichlor formula, which combines a built-in UV stabilizer and near-neutral pH to maintain free chlorine levels longer while reducing the need for extra chemical adjustments. For anyone seeking a seasonal, easy-to-use granular chlorine that dissolves quickly and protects liners, this is a practical choice.

Key Features

• Stabilized formula: The dichlor resists UV breakdown so chlorine stays active longer under sun exposure, reducing the frequency of reapplication.
• pH neutral: Because the product is essentially pH neutral, pool owners will generally make fewer pH corrections after dosing compared with other chlorinating supplies.
• Fast dissolving: The granular form dissolves quickly in a 4-ft column so it disperses without leaving residue or risking bleach damage to liners the way tablets can.
• Multi-purpose action: It functions as a sanitizer, algaecide, and disinfectant, cutting down the number of separate chemicals required for routine maintenance.
• Concentrated active ingredient: Being 99% sodium dichloro-s-triazinetrione equivalent makes the product effective at establishing and maintaining chlorine levels for safe swimming.

Who It's For

Pool and spa owners who prefer a granular, stabilized chlorine that dissolves quickly will appreciate this formula, particularly those with outdoor pools that receive strong sun and benefit from UV resistance. It is also a good fit for hot tub users who want a sanitizer that is less harsh on skin due to the dichlor chemistry.

People who need a single-tablet-style slow-release solution or those who require non-stabilized shock-level chlorination for immediate, aggressive treatments should look elsewhere. Also, users expecting identical dissolution behavior in every situation should note that some customers report variable dissolve speed depending on dosing method and water movement.

Pros & Cons

Pros

• Maintains clearer water longer because the stabilizer slows UV degradation.
• pH neutral chemistry reduces the need for frequent pH adjustments.
• Quick dissolution when added correctly, making it convenient for routine daily maintenance.
• Effective as a sanitizer, algaecide, and disinfectant so fewer separate chemicals are required.

Cons

• Some users report variability in how quickly granules dissolve, so technique and circulation matter.
