Detailed Description
Fi-Clor Ultra Concentrated Algicide 1 litre

Fi-Clor 1 Ltr Ultra Concentrated Algicide-Copper Free - Quick Overview

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 volume of water in your pool if in doubt refer to the Fi-Clor Swimming Pool Handbook in our downloads section.

In hard water areas, increase the initial dosage 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 bucket, 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.
