Product Information

Full details

Blue Horizons Flockfix Cartridges are designed for pool owners who struggle with cloudy water caused by fine debris that standard filters miss. These cartridges provide a convenient, slow-release method to aggregate small suspended particles and remove metals, resulting in significantly improved water clarity. Please note that for optimal effectiveness, users must maintain specific water chemistry parameters, particularly the pH level, or the flocculant will not perform as expected.

FAQs

How many cartridges do I need for my pool?

Use one 125g cartridge per 50,000 litres of pool water each week.

Can I use this with a cartridge filter?

These cartridges are primarily designed for sand filter systems. Check your specific filter manufacturer instructions regarding the use of flocculants.

What happens if my pH is not in the 7.2–7.6 range?

The flocculant will not bind particles effectively, and you may see little to no improvement in water clarity.

Do I need to turn the pump off to insert the cartridge?

It is safer to turn the pump off while placing the cartridge in the skimmer basket to prevent any suction-related issues, then restart the pump immediately after.

Does this product remove all pool metals?

It aids in the removal of copper, iron, and manganese, but for severe metal contamination, a dedicated sequestering agent may be required.

Can I swim immediately after adding the cartridge?

Yes, once the cartridge is placed in the skimmer and the system is running, the concentration of chemicals is generally safe, provided your chlorine and pH levels are balanced.

Troubleshooting

Water remains cloudy after 48 hours

Check and adjust your pH and alkalinity levels. If they are outside the recommended range, the flocculant will not be effective.

Filter pressure rising too quickly

This is normal as the product is capturing fine particles. Backwash your filter immediately to clear the debris and restore flow.

Cartridge not dissolving

Ensure there is adequate water flow through the skimmer basket. If the pump is turned off for extended periods, the cartridge will not dispense.

Pros and Cons

Pros

Simple, pre-measured dosage removes the need for liquid chemical handling
Effective at clearing up fine haze that passes through standard sand filters
Helps manage metal content to prevent staining and water discolouration
Easy to use by simply placing into the existing skimmer basket

Cons

Requires strictly balanced water chemistry to function properly
Cannot be used in all filter types (check manufacturer filter guidelines)
Requires a backwash or filter clean after the debris is trapped
Limited effectiveness if pH levels drift outside the recommended range

Setup, Compatibility & Care

Before using the cartridges, you must test your pool water to ensure it falls within the following ranges: pH between 7.2 and 7.6, total alkalinity between 80 and 150mg/l, and free chlorine levels between 1 and 3mg/l. If these levels are not met, the product may not perform effectively. Always backwash your filter and clean the skimmer basket thoroughly before introducing a new cartridge to ensure optimal water flow. Use one cartridge per 50,000 litres of pool water on a weekly basis. Store unused cartridges in a cool, dry place away from direct sunlight and moisture to maintain the integrity of the slow-release material.
