Fi-Clor 4kg Superfast Shock

£58.85 £51.00

Kills water-borne bacteria. Fast dissolving & fast acting.

Fi-Clor Superfast granular hypochlorite can be used as a regular pool sanitiser – it is especially recommended for pools that are open all year round. Superfast contains 10% more available chlorine than standard calcium hypochlorite and its fine particle size enables you to dose it directly into the pool rather than pre-dissolve. It dissolves rapidly to form active free chlorine to kill bacteria and help control algae. Superfast granules contain calcium which helps balance soft water, and it is stabiliser-free so avoiding the problem of 'chlorine lock'.


Calculate the volume of water in your pool (if in doubt, consult the Fi-Clor Swimming Pool Handbook).

For maximum efficiency stabilise the water at the beginning of the season with Fi-Clor Chlorine Stabiliser. Alternatively, use the product in conjunction with Fi-Clor Premium 5 multi-functional stabilised chlorine tablets which will give sufficient stabiliser to guarantee optimum performance after a short period of use. (Do not mix these products – dose them into the pool from separate locations e.g tablets in the skimmer, Superfast Granules dosed directly into the pool). Test the water daily

The dosage may vary depending upon water conditions, circulation rate, time of day and geographical location. Broadcast the product evenly over a wide area in the deepest part of the pool. Test the water and adjust the dose as necessary.

Superchlorinate the water at least every 2 weeks using 350g per 11,000 gallons (50 m3) of pool water.
