Pool chlorine shock Marimex Chlor Šok 2,7 kg - concentrated pool chemical for algae treatment

Marimex Chlor Šok 2,7 kg is a concentrated pool chlorine shock formulation designed to quickly increase free chlorine levels and combat algae in swimming pools. This product is intended for periodic shock dosing to clear cloudy water, oxidize organic contaminants and restore sanitary conditions after heavy use or algal blooms. The granular composition dissolves to release active chlorine for rapid disinfection and algae control.

Advantages

Concentrated formula delivers a fast rise in free chlorine, enabling quick treatment of visible algae and cloudy water. The product works both to disinfect and to oxidize organic matter that causes turbidity, helping filters and clarifiers perform more effectively. Its granular form allows for measured dosing and relatively simple application when used according to directions.

Suitable for

• Shock treatment after heavy bather load or storm-related contamination
• Rapid response to visible algae growth
• Periodic intensive sanitizing cycles in outdoor and indoor pools
• Preparation of a pool for long-term closure or re-opening after stagnation

When it may not be suitable

This concentrated chlorine shock is not intended for continuous low-level chlorination; it should be used as an occasional intensive dose. It may not be suitable for pools with sensitive finishes, certain types of natural stone coping, or plumbing and equipment incompatible with high chlorine concentrations—verify compatibility before use. Do not use in conjunction with other pool chemicals unless directions indicate it is safe to do so.

Key specifications

• Form: Granular concentrated chlorine shock
• Net weight: 2.7 kg
• Primary action: Rapid increase of free chlorine and oxidation of organics
• Intended use: Periodic shock dosing for algae control and water clarification
• Application environment: Suitable for both outdoor and indoor swimming pools

How to use

Measure the required amount based on pool volume and the severity of contamination, following the dosing guidance on the product label. Pre-dissolve if recommended by the manufacturer, then distribute evenly around the pool while the pump and filtration are operating to promote circulation. Allow sufficient contact time for chlorine to oxidize organics and neutralize algae; test free chlorine and pH levels before re-entry and adjust as needed. Maintain proper filtration and backwash or clean the filter after treatment to remove debris.

What to consider before purchase

• Pool volume to determine correct dosing quantities
• Compatibility with pool finish, piping and equipment
• Storage requirements: keep in a cool, dry, well-ventilated place away from incompatible substances
• Need for protective equipment when handling concentrated chlorine (gloves, eye protection)

Usage recommendations

Use this product only as directed on the label. For best results, balance pH and stabilizer levels before shock dosing, ensure good circulation during and after application, and retest water before allowing swimmers back into the pool.
