    Instructions To Correct Low Chlorine Levels in Swimming Pools using Fi-Clor Stabilised Chlorine

    Calculate your pool water volume, if in doubt use this link to our Swimming Pool Chemical Handbook to use the handy swimming pool volume calculator.

    Test your pool water using your prefered testing method. If the chlorine level is lower than 1ppm you will need to raise it.

    Dose rate: 18g Per 10m3 (10,000 litres / 2,200 UK Gallons) will raise the pool water 1ppm

    If Dosing directly into the pool avoid inhaling Fi-Clor Stabilised Chlorine Granules dust blown by the wind.

    Pre-dissolve the granules if the water is cold or not circulating, such as when the pool is closed for the winter.
