Quickly eliminate cyanobacteria and their toxins

Cyanobacteria (often mistakenly called "blue-green algae") can make a natural pond unsafe for swimming, severely disrupt the ecosystem, and produce toxins harmful to humans, pets, and aquatic wildlife.

• Simultaneously increases the oxygen content of the water.
• Very long shelf life storage
• Easy dosing & very simple spreading

CyanoClear OASE is a professional solution specially developed to quickly eliminate cyanobacteria blooms while neutralizing the cyanotoxins they release.

Thanks to its powerful oxidation mechanism, CyanoClear acts directly on the cellular structure of cyanobacteria without leaving persistent residues in the aquatic environment.

CyanoClear exploits the natural behavior of cyanobacteria that rise to the surface to perform photosynthesis. The granules act directly where they are most concentrated, greatly improving its effectiveness.

Why choose CyanoClear?

✅ Effectively eliminates cyanobacteria

✅ Neutralizes cyanotoxins in less than 48 hours

✅ Fast action upon application

✅ No persistent residues

✅ Helps restore a healthy biological balance

✅ Suitable for natural ponds, lakes, water bodies, and basins

A particularly effective dual action

Immediate action

Upon application, CyanoClear triggers an oxidation reaction that quickly destroys the cells of cyanobacteria responsible for water discoloration and toxin production.

Action on toxins

At the same time, the product neutralizes cyanotoxins released into the water, helping to improve safety for:

• swimmers,
• dogs and other animals,
• fish,
• aquatic biodiversity.

A technology based on sodium percarbonate

CyanoClear gradually releases hydrogen peroxide, known for its effectiveness against cyanobacteria. After its action, it naturally breaks down into water and oxygen, leaving no persistent residues.

💡 Expert advice: to speed up the action of CyanoClear, we recommend combining it with an Aquitechnics surface aerator. Water circulation improves the distribution of the treatment, and the first results are often visible within minutes.

Promotes the return of a balanced ecosystem

When cyanobacteria take over, they gradually suffocate aquatic life. 

By reducing their proliferation, CyanoClear helps promote:

• the development of beneficial phytoplankton,
• the return of zooplankton,
• better water quality,
• a more stable ecosystem.

The first effects are visible just minutes after application. Toxins are typically neutralized within 48 hours with the addition of a suitable aerator. 

Efficiency

25 kg bucket

✔ Treats up to 400m² of water surface.

Application advice

For best results:

• Apply strictly in the morning;
• Distribute the product evenly over the water surface;
• Avoid spreading directly on aquatic plants;
• Follow the recommended doses according to the level of cyanobacteria proliferation.

The product can be used on swimming ponds, water bodies, and fish ponds, following the manufacturer's usage recommendations.

Technical specifications

Why buy your CyanoClear from Foudebassin.com?

At Foudebassin.com, we have been supporting owners of natural ponds, water bodies, and natural swimming areas facing cyanobacteria blooms for many years.

In case of a major invasion, our specialists can also advise you on additional measures to sustainably limit their recurrence (aeration, biological balance, nutrient reduction, phosphate management…).

Why is CyanoClear the best treatment?

• Works within minutes.
• Also neutralizes cyanotoxins (not just cyanobacteria).
• Naturally breaks down into water and oxygen.
• Does not accumulate residues in the pond.
• Acts exactly where cyanobacteria develop: on the water surface.
• Professional technology developed by OASE Professional.
• Suitable for natural ponds, lakes, and large water bodies.

💡 Advice from our experts

The treatment eliminates the cyanobacteria present, but their return depends on the causes that favored their development (high temperature, stagnant water, excess nutrients, lack of oxygen, etc.). For lasting results, it is often recommended to also act on the overall balance of the pond in addition to the treatment.

Why do cyanobacteria appear?

Cyanobacteria (often mistakenly called blue-green algae) develop when several factors combine: high temperatures, stagnant or insufficiently circulated water, excess nutrients (notably phosphates and nitrogen), low oxygen levels, and strong sunlight. Under these conditions, they can quickly colonize the water surface, form greenish or blue-green mats, and produce cyanotoxins potentially dangerous to swimmers, pets, fish, and the entire ecosystem. It is therefore essential to intervene at the first signs to avoid massive proliferation, swimming restrictions, or significant water quality degradation.

A professional technology validated in the field

Developed by OASE Professional, CyanoClear is used to treat natural ponds, lakes, recreational water bodies, and large aquatic sites. Its effectiveness has been demonstrated in trials conducted on water bodies heavily affected by cyanobacteria, with results observed very quickly after application. Independent scientific studies, notably conducted by the University of Debrecen, also confirm its effectiveness against cyanobacteria while preserving biological balance when used according to recommendations. For lasting results, it is however recommended to also address the causes of their appearance, notably by improving oxygenation, water circulation, and nutrient management to reduce the risk of recurrence.

💡 Advice from our Foudebassin experts: a treatment eliminates the cyanobacteria present, but it alone does not remove the conditions that favored their development. Combining CyanoClear with good surface or bottom aeration, as well as managing phosphates and organic matter, generally offers the best long-term results.
