PoolBrite Whamo Shock Plus 450g

PoolBrite Whamo Shock Plus 450g provides a potent instant chlorine boost that effectively destroys organic contaminants and restores brilliant water clarity.

This easy-to-use treatment is the ideal quick-fix for pools following heavy swimmer loads or seasonal storms, ensuring a safe and sparkling swim.

Product Specifications and Features

• • Contains a proprietary blend of calcium hypochlorite and water-clarifying agents for a comprehensive water recovery solution.
• • Designed with a fast-dissolving granular texture that minimises the risk of bleaching pool surfaces when applied correctly.
• • Packaged in a single-use four hundred and fifty gram sachet, providing the ideal dosage for a standard fifty thousand litre pool.
• • Functions as a powerful oxidiser to break down chloramines, which are responsible for the unpleasant chlorine smell and eye irritation.
• • Formulated to be compatible with both standard chlorine and salt-water pools needing a supplementary sanitiser boost.

Ideal Use and Instructions

• • Specifically intended for use as a shock treatment after high-traffic pool parties, heavy rain, or when water appears dull.
• • Always test the water first to ensure the potential hydrogen is between seven point two and seven point six for maximum chemical performance.
• • With the pump running on the filter or circulate setting, sprinkle the granules evenly over the water surface around the deep end.
• • Avoid adding the product through the weir or skimmer box to prevent concentrated chemical contact with the filtration equipment.
• • Brush the pool floor immediately after application to ensure any undissolved granules are moved and fully integrated into the water.

Safety Precautions

• • This is a highly reactive chemical; do not mix it with any other pool products, especially different types of chlorine or acids.
• • Wear protective gloves and eye protection when opening the sachet to prevent chemical dust from contacting your skin or eyes.
• • Store any unopened sachets in a cool, dry place away from flammable materials, direct sunlight, and heat sources.
• • In the event of accidental skin contact, wash the affected area immediately with large quantities of fresh running water.

Frequently Asked Questions

• • How soon can we swim? It is recommended to wait at least twelve hours or until the chlorine level has dropped back to below three parts per million.
• • Will this clear green water? Yes, it is an effective first step for killing algae, though severe cases may require a double dose or additional algaecide.
• • Is it safe for vinyl-lined pools? Yes, provided the granules are pre-dissolved in a plastic bucket of water before application to prevent liner bleaching.
• • Can I use this at night? Applying shock treatments in the evening is preferred as sunlight dissipates chlorine, allowing the product to work more effectively overnight.

Pro Tip for Local Pool Care

• • If your pool water looks dull, use your Whamo Shock Plus in conjunction with a backwash and rinse cycle.
• • Shocking the pool just before a long filtration cycle helps the oxidised debris get caught in the filter sand much faster, and adding a small amount of gel flocculant to the weir afterwards will help your sand filter trap the fine dust that usually passes right through.
