The professional solution against excess phosphorus, algae blooms, and cyanobacteria
When algae keep coming back despite treatments, the problem is often much deeper.
- 5KG treats 100M³
- 10KG treats 200M³
- 25KG treats 500M³ of water
In most natural ponds, excess phosphorus acts as a true fuel for algae, cyanobacteria, and invasive aquatic plants. Even after their apparent disappearance, this phosphorus remains in the water and sediments… ready to trigger a new proliferation.
OASE SeDox Max was developed to sustainably break this vicious cycle.
Thanks to its next-generation patented technology, it captures and permanently immobilizes phosphorus, both that present in the water column and that released by sediments. Unlike many temporary solutions, the phosphorus becomes biologically unavailable and can no longer feed algae.
Why is SeDox Max different?
SeDox Max does not just make the symptoms disappear.
It acts directly on the main cause of eutrophication.
Its exclusive mineral formulation allows to:
✅ Permanently immobilize dissolved phosphorus
✅ Block phosphorus released by sludge
✅ Rebalance the natural Carbon / Nitrogen / Phosphorus (C:N:P) ratio
✅ Promote more stable and clearer water
✅ Improve living conditions for beneficial bacteria
✅ Limit future algae and cyanobacteria blooms
By gradually restoring the biological balance of the water body, SeDox Max sustainably improves water quality and encourages the return of a healthier ecosystem.
The benefits of SeDox Max
- ✔ Permanently captures phosphorus
- ✔ Acts in the water and in the sediments
- ✔ Greatly reduces the risk of new algae blooms
- ✔ Helps combat cyanobacteria by removing their main nutrient source
- ✔ Promotes better water clarity
- ✔ Compatible with aquatic fauna and flora
- ✔ Professional mineral solution developed by OASE
- ✔ Suitable for ponds, lakes, reservoirs, golf courses, private estates, communities, and natural water bodies
A much more sustainable approach than traditional treatments
Algaecides generally destroy algae already present.
But when they decompose, they often release a new amount of phosphorus into the water, fueling a new cycle of proliferation.
SeDox Max works differently.
It gradually removes phosphorus from the biological cycle by transforming it into a stable and insoluble mineral form. Algae then no longer have their main nutrient to develop.
Ideal as a complement to surface aeration
For the best results, we strongly recommend combining SeDox Max with a high-performance surface aerator.
Aeration improves:
- water oxygenation
- natural bacterial activity
- the degradation of organic matter
- the biological stability of the water body
The combination of the two technologies is today one of the most effective approaches to sustainably restore a natural pond.
In which cases to use SeDox Max?
SeDox Max is especially recommended when your water body shows:
- persistent green water
- recurrent algae blooms
- cyanobacteria
- a high phosphate level
- nutrient-rich sediments
- advanced eutrophication
- a decline in biodiversity
- poor water quality
Perfectly suitable for
- Natural ponds
- Private lakes
- Fishing water bodies
- Private estates
- Nature reserves
- Golf courses
- Parks
- Communities
- Retention basins
- Wetlands
Why is phosphorus the real problem?
In most freshwater bodies, phosphorus is the limiting nutrient.
When it becomes too abundant, it acts as a true natural fertilizer that promotes:
- filamentous algae
- green waters
- cyanobacteria
- invasive aquatic plants
Even if these organisms disappear, phosphorus remains in the system and can quickly trigger a new bloom.
It is precisely this cycle that SeDox Max allows to interrupt permanently.
Why choose OASE SeDox Max?
✔ Developed for heavily eutrophicated water bodies
✔ Professional technology used in lake restoration programs
✔ Long-lasting impact on water quality
✔ Compatible with ecological management of aquatic environments
✔ Ideal solution within a comprehensive natural pond restoration strategy
⭐ Expert Advice in Aquatic Environments
For a complete pond restoration, we recommend combining:
-
SeDox Max to permanently immobilize phosphorus.
- A professional surface aerator to improve oxygenation and stimulate beneficial bacteria.
- Specialized bacteria when sediments are heavily loaded with organic matter.
This approach simultaneously acts on the nutrients, oxygen, and biology of the water body, offering results that are significantly more sustainable than an anti-algae treatment alone.
