This active oxygen powder brings filamentous algae, sludge and leaves up to the surface of a congested pond, and you then scoop them out with a net. Dose it at 60 g per cubic metre once the water is above 14 °C, leaving at least 15 days between applications.

The summary
- What you receive: an effervescent powder to sprinkle on, in five pack sizes matched to your pond volume, from 3,000 to 40,000 litres.
- What it does: it releases active oxygen, loosens sludge and string algae, and brings them up to the surface.
- Dosage: 60 g per cubic metre, that is 4 scoops of 15 g or 2 of 30 g per 1,000 litres.
- When to treat: as soon as the water rises above 14 °C, with at least 15 days between two applications.
- Shock or maintenance: this one is dosed by volume and works within a few hours. The bioactive anti-string-algae cleaner is dosed by surface area, every 15 days.
- Storage: 6 months after opening, kept dry, between 10 and 25 °C.
Active oxygen powder that brings sludge and filamentous algae up to the surface
The Biobooster+ shock treatment against algae and sludge is an active oxygen powder that loosens sludge and filamentous algae in an ornamental pond and brings them to the surface within a few hours. It is dosed at 60 g per cubic metre, as soon as the water exceeds 14 °C, and the material that has risen is then removed with a net.
You have a pond overrun with green strands, a bottom covered in sludge and rotting leaves. This powder is sprinkled over the surface, releases active oxygen on contact with the water, and brings the organic matter to the surface within a few hours. Collection then begins, because everything that floats must be removed from the pond before it sinks back to the bottom.
🫧 What the fizzing stirs up
The active oxygen attacks organic matter by oxidation, with no copper or zinc, and the product is non-biocidal. A foam forms on the surface during the treatment, which is normal and temporary. Your water may also turn cloudy for a few days after treatment, while the fine particles that have been dislodged settle again or are caught by the filter. None of this calls for a second treatment: let the filtration run and keep an eye on the water over those few days.
🌡️ The 14 °C threshold
The treatment waits until the water rises above 14 °C. Below that, the reaction is too slow to justify a dose, and you spend product for nothing. Then allow at least 15 days between two applications, which sets the pace of the season: if the water turns cloudy again 8 days after a treatment, observe it before treating again. Measure the water temperature rather than the air temperature, using a floating thermometer.
Before
Remove branches and whole leaves by hand, and check that the filtration and aeration are running.
During
Sprinkle the powder over the whole surface, undiluted, concentrating on areas with filamentous algae.
After
Scoop out everything that has floated up, within a few hours.
What extends the treatment
A shock treatment removes the matter that rises to the surface. It does, however, leave fine residues in the water, which the net does not catch. A dose of concentrated bacteria in powder form, 4 to 5 days later, establishes a population that digests these residues within a few weeks.
The ornamental pond, not the growing circuit
This product is designed for an ornamental garden pond. Keep it for your water feature, and not for a circuit that feeds edible crops. If you are looking to maintain the balance of an aquaponic system, the options are described in the article on pH regulation in aquaponics, and the bacterial input comes from the liquid activator poured into the filter.
🥄 60 grams per cubic metre
The dose is 60 g per 1,000 litres, which is 4 scoops of 15 g or 2 of 30 g. Work out the real volume of your pond by multiplying length by width by average depth in metres, then multiply by 1,000. A pond measuring 4 m by 3 m with an average depth of 0.8 m therefore holds 9,600 litres, and needs 576 g. The five pack sizes, from 3,000 to 40,000 litres, are calibrated to these volumes, with the smallest 180 g tub covering a 3,000-litre pond. Stored dry, between 10 and 25 °C, an opened pack keeps for 6 months.
🔁 Why the algae come back
A shock treatment removes the algae already present, but it does not remove what feeds them. The green filaments live on dissolved phosphorus and nitrogen, brought in by dead leaves, by the fish ration and sometimes by the top-up water itself, and as long as that source keeps flowing, regrowth is a matter of weeks. The sequence that lasts a whole season therefore combines three steps: the treatment to regain control, the bacterial seeding to digest what remains, then cutting the input at source, through more accurate feeding and regular removal of fallen leaves. A phosphate test carried out on the pond water and then on the top-up water will tell you whether the latter is already supplying phosphorus, and a reading that stays high after a treatment almost always points to the top-up water or an excessive ration rather than a shortage of product.

Two ways to recover filamentous algae
One is dosed by volume and works within a few hours, the other is dosed by surface area and has to be repeated.
A knock, or repeated maintenance
A full-blown infestation is dealt with in one go. Filaments that come back every fortnight are treated at the pace at which they return.
