    PRODUCT INFO: Fi-Clor Alkalinity Increaser is used for raising the Alkalinty levels in your swimming pool. Maintaining the correct Alaklinity levels in the swiming pool water is important as low Total Alkalinity levels may  cause any chemicals added to the water to alter the pH level.

    Total Alkalinity is the measure of carbonates & bicarbonates in the water. Ensuring it is correct will reduce pH fluctuations.

    Instructions To Correct Low Alkalinty Levels in Swimming Pools & Hot Tub Spas using Fi-Clor Alkalinity Increaser

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

    Test your water using your prefered testing method. If lower than 100ppm you will need to raise it

    Dissolve the amount suggested on the label of Fi-Clor Alkalinty Increaser in a 10 litre bucket. Do not dissolve more than 500g at any one time. If more than 500g is required repeat the process.

    With the pumps running pour the mixture evenly around the pool, but not into the skimmers.

    Leave the filtration running and re-check the Alkalinity levels after 24 hours. If the level is still low re-dose with Fi-Clor Alkalinity Increaser until the level is correct.
