Fi-Clor Maxi-Tabs.
Fi-Clor Maxi-Tabs, unrivalled in quality, are designed to slowly release a safe but highly concentrated level of available chlorine over a period of several days to combat bacteria and other pollutants. Because they contain a built-in stabiliser, they are ideal for outdoor pools where loss to sunlight can be a problem.

Instructions.
> Calculate the volume of water in your pool (if in doubt, consult the Fi-Clor Swimming Pool Handbook).
> Remove plastic wrapping and place the Maxi-Tabs in skimmer basket or tablet feeder. > School, hotel or public pool feeder requirements will vary, depending on water capacity, water temperature, flow rate and number of bathers. Adjust dosage to maintain correct free chlorine readings.
