Directions To minimize bleaching, pre dissolve required amount of Aqua Shock in a plastic pail with concentration not exceeding 1kg per 10L of water. Always add chemical to water, NEVER water to chemical. Broadcast resulting slurry directly to pool water. Initially, superchlorinate pool water with 150g of Aqua Shock per 10,000L of pool water. For best results, superchlorinate at dusk. Maintain proper chlorine residual by broadcasting daily over the pool's surface, 30g of Aqua Shock per 10,000L of pool water, or as needed. Note: Hot weather, heavy pool usage, and rain may require higher usage rates to maintain proper chlorine residuals. Superchlorinate weekly using 150g of Aqua Shock per 10,000L of pool water when average daily temperature is 25 - 32 degrees celsius. Otherwise, superchlorinate every other week. For visible algae, superchlorinate using 350g of Aqua Shock per 10,000L of pool water. Heavy algae infestation may require dosages up to 500g per 10,000L. Vacuum pool when dead algae settles. NOTE: For outdoor pools, chlorine residuals can be protected from destruction by sun's rays by addition of stabilizer (cyanuric acid).
