The Oase AquaActiv PhosLess is designed for pond owners looking to manage algae growth by proactively controlling nutrient levels. It is ideal for those maintaining ornamental or fish ponds who want a chemical-free way to bind excess phosphates, heavy metals, and sulphides. While it is highly effective at improving water quality, users must commit to replacing the inserts every 6-8 weeks to ensure continuous phosphate removal and prevent saturation.

Yes, it is designed for use in aquatic environments and is safe for pond ecosystems when used as directed.
One pack is effective for up to 10,000 litres of water, based on an initial concentration of 5 mg of phosphate per litre.

No, PhosLess is a chemical/adsorption filter media and should be used alongside mechanical and biological filtration.
No, it is safe for pond plants and specifically targets algae-promoting nutrients.
Check if the granulate has been in the water for more than 8 weeks; it may be saturated and require replacement.
Ensure the granulate is not packed too tightly and that the filter media is free from heavy organic sludge buildup.
Ensure the material is secured in a proper mesh bag or filter housing within an area of moderate water flow.
Setup is straightforward: simply rinse the granulate gently before initial placement to remove any fine dust. If using inside a Biotec filter, slide the inserts into the media housing until secure. To maintain efficacy, mark your calendar for a replacement every 6 to 8 weeks. When removing saturated units, dispose of them by mixing the contents into your garden soil as a fertilizer, as the bound phosphates are still beneficial for terrestrial plants. Keep the product stored in a cool, dry place before use to maintain the integrity of the filter media.
