HTH Shock It Pool Care Treatment 500g

The HTH Shock It Pool Care Treatment 500g is a fast-acting, non-stabilised chlorine treatment used to rapidly sanitise and clarify swimming pool water. This high-strength calcium hypochlorite formula effectively superchlorinates the water to eliminate organic contaminants, bacteria, and algae blooms, restoring a hygienic and sparkling blue environment for residential pools after heavy usage or summer storms.

Ideal Use and Application

• • Water Restoration: Specifically designed for "shocking" the pool to resolve issues like cloudy water, dull appearance, or algae growth.
• • Non-Stabilised Formula: Since it contains no cyanuric acid, this pool shock will not increase your stabiliser levels, helping to prevent the common issue of chlorine lock.
• • Fast Dissolution: The granular format is engineered for rapid action, meaning it begins working immediately upon contact with the water.
• • Post-Storm Recovery: Ideal for use after heavy South African rainstorms or wind to neutralise external contaminants and organic debris washed into the pool.
• • Versatile Compatibility: Safe for use in all pool types, including marbelite and fibreglass, when applied correctly according to the volume of the pool.

Safety Precautions

• • Application Time: Always apply the treatment during the evening or at night; UV rays from the sun significantly reduce chlorine effectiveness during the day.
• • Handling: Wear protective gloves and eyewear; do not breathe in the dust or fumes when opening the 500g pouch.
• • Mixing Warning: Never mix this product with any other pool chemicals (especially stabilised chlorine or acids) as it can cause a dangerous chemical reaction or explosion.
• • Swimming Gap: Do not enter the pool immediately after application; wait until the free chlorine level has dropped back to between 1 ppm and 3 ppm.

Frequently Asked Questions

• • How often should I use pool shock? It is recommended to shock your pool once a week for maintenance, or immediately after a high swimmer load or heavy rainfall.
• • Does this product bleach pool linings? To avoid bleaching, it is best to pre-dissolve the granules in a bucket of water or brush them immediately after broadcasting to ensure they do not settle on the floor.
• • Can I use this with a salt chlorinator? Yes, it is compatible with salt systems and can be used as a "boost" if the chlorinator is struggling to keep up with high temperatures.

Local Pro-Tip

• • In high-heat regions, your pool can "turn" in less than 24 hours. If you notice a slight slippery feel on the pool walls before the water actually looks green, use one 500g bag of Shock It immediately; it's a much cheaper "save" than having to treat a fully black or green algae-infested pool later.
