This quickly dissolves and provides an easy-to-use chlorine shock treatment for swimming pool water, eliminating bather wastes, contaminants, and algae. With its high chlorine content, Castle Hot Tubs 5kg Granular Shock quickly establishes a chlorine level in your pool water.

Use these non-stabilised chlorine shock granules to commission new swimming pools or for regular oxidation of swimming pool water.

The 1 kg tub includes dosing rates and full directions for use on the packaging.

Shock treat the pool water every fortnight, or more frequently in hot weather, by adding granular shock.

Apply this product if you notice algae growth on the walls or floor of the pool or after an exceptionally high level of bather load.

Instructions for using Granular Shock:

Maintain pH levels within the ideal range of 7.2-7.6. Adjust the level if it is not in this range. Maintain free chlorine residuals within the range of 1 – 3 mg/l (ppm).

Add the product at a rate of 110g per 10m3 of pool water.

Pre-dissolve Castle Hot Tubs 5kg Granular Shock in a clean plastic bucket filled with clean, warm pool water, at a maximum rate of 100g of product per 2.2 gallons / 10 litres of water. Always add the product to water, not water to the product.

Ensure the pool circulation pump is running before you slowly pour the solution immediately above the pool return.

Never mix this product directly with other pool chlorine products. Do not pour it into a pool skimmer containing chlorine tablets.

Never add this product when people are using the pool. After treatment, wait a minimum of 30 minutes before using the pool.

Wait until the chlorine residual has dropped to 3 parts per million before allowing people to use the pool.
