HELPS PREVENT OR TREAT ALGAE. Highly concentrated to prolong contact with affected areas. Dual action algicide and clarifier. Compatible with all sanitisers and filters.

1 litre of this product is equivalent to 3 litres of standard algicide.


  • Calculate the water volume of your pool (if in doubt refer to the Fi-Clor Swimming Pool Handbook).
  • In hard water areas, increase the initialdosage by 50%.
  • In the event of large numbers of bathers, high temperatures or heavy rain, increase the dosage.

Pools that have been emptied:

  • Clean the pool surfaces thoroughly.
  • Using a clean, uncontaminated pail, make up a solution using 1 part Ultra Concentrated Algicide to 10 parts water.
  • Thoroughly wash skimmers, bottom drains, outlets and liner or tile joints. Leave for about an hour before filling the pool.

Treating water that has turned green:

  • For maximum performance, adjust the pH to approx 7.2.
  • Shock dose the pool with Fi-Clor Superfast Shock at the rate of 1.1kg per 11,000 gallons (50m3) (accuracy of dosing is not important).
  • Broadcast the product evenly over a wide area in the deepest part of the pool and keep the circulation running.
  • Allow time for the shock to disperse, then add Ultra Concentrated Algicide either via the skimmer, or directly into the pool at a rate of 650ml per 11,000 gallons (50m3) Ensure there is no other product in the skimmer nor any bathers in the pool.
  • Leave the product to act for 1-2 hours then brush off any algae that may be clinging to pool surfaces and agitate any areas where concentrations of product may still exist.
  • Run the filter for 24 hours then backwash to remove dead algae from the top of the filter media.
