Note: If the pool is below 19ºC (65ºF) or if your pool is less than 1.3 metres deep then this product should be pre-dissolved in a clean plastic container with warm water.
Pour solution evenly around the perimeter of the pool with the circulation running.

the ideal range of 1-3mg/l (ppm) then pool use can recommence.
