• Restores Water Clarity – Oxidizes organic waste and chloramines for clearer, cleaner-looking pool water

• Saltwater Compatible – Safe for use in saltwater pools and does not interfere with salt chlorine generators

• Granular, Fast-Dissolving Shock – Dissolves quickly for efficient distribution and reliable performance

Effective pool sanitation isn’t just about adding chlorine—it’s about maintaining water clarity, eliminating contaminants, and keeping sanitizer levels stable over time. Poolife NST Purify Swimming Pool Shock is a stabilized dichlor shock designed as Step 2 in the Poolife NST (No Scale Technology) system, providing fast-acting oxidation and consistent chlorine support without overstressing pool surfaces or equipment.

This granular dichlor shock is formulated to destroy organic contaminants, bacteria, and algae while simultaneously restoring clarity to cloudy pool water. Because it is stabilized, NST Purify protects chlorine from rapid breakdown due to sunlight, making it especially effective for outdoor pools that struggle to maintain sanitizer levels.

At Benchmark Pool Supply, NST Purify is commonly recommended for routine shocking, cloudy water recovery, and ongoing maintenance within the Poolife NST program. It delivers reliable performance without the harsh side effects associated with some high-strength shock treatments.

What Makes Dichlor Shock Different

Not all pool shock is the same. Dichlor shock provides both oxidation and usable chlorine, meaning it actively sanitizes while it cleans. Unlike calcium hypochlorite shock, dichlor dissolves quickly and completely, leaving no residue behind and avoiding unwanted calcium buildup.

Poolife NST Purify Swimming Pool Shock uses stabilized dichlor to deliver fast results while helping maintain consistent free chlorine levels. This makes it an excellent choice for regular shock treatments, especially in pools where water balance and surface protection are priorities.

Step 2 in the Poolife NST System

Poolife NST Purify plays a specific role within the NST water care system. As Step 2, it is designed to work in coordination with other NST products to maintain clean, balanced water while minimizing scale formation and surface wear.

Used as directed, NST Purify supports ongoing sanitation, improves water clarity, and enhances overall system efficiency without requiring excessive chemical adjustments.

When to Use Poolife NST Purify Shock

This dichlor shock is ideal for a wide range of routine and corrective applications, including:

• Weekly or bi-weekly shock treatments

• Cloudy or dull water recovery

• After heavy swimmer load or pool parties

• Following rain, wind, or debris events

• As part of a structured NST maintenance program

Because it dissolves quickly and evenly, it begins working almost immediately after application.

Gentle on Pools, Tough on Contaminants

One of the key advantages of Poolife NST Purify Swimming Pool Shock is its balanced approach. It is tough on bacteria, algae, and organic waste but gentler on pool surfaces and equipment compared to harsher shock options. This makes it suitable for pools with vinyl liners, plaster finishes, and modern equipment systems.

When used according to label directions, it helps maintain water clarity without contributing to scaling or cloudy residue.
