Fighting algae in ponds and basins
Dealing with algae in a pond can sometimes be difficult, but with the right habits and the right products on hand, you can keep your pond water clear and healthy. In our “Algae Control” category, you will find products specially designed to limit the growth of filamentous algae and floating algae, the two most common types of algae in ponds.
The most common algae in ponds
Floating algae, which turn your pond water green, can be treated in the short term with a flocculant. However, for an effective long-term treatment, we recommend installing a UV lamp suited to your water volume. It helps curb the algae suspended in the water before they even develop, so you can enjoy clear and healthy water.
If you are dealing with filamentous algae, it is important to start by testing the water quality of your pond. Once you have corrected the hardness levels if necessary, you can use an algae treatment specifically designed for filamentous algae. It is important to keep your pond well oxygenated during treatment to avoid stressing fish and plants.

The solutions available in our algae control section:
- Water testing kits to help you determine the hardness levels of your water
- Flocculants for short-term treatment of floating algae
- UV-C lamps for effective long-term treatment
- Anti-algae treatments specially designed for filamentous algae
- Pond bacteria that help maintain the biological balance of the water.
- Aerators to maintain a sufficient oxygen level in your pond during treatment
- Fine-mesh nets to remove dead algae from your pond
Our team is always available to answer your questions and help you choose the products best suited to your situation. Do not hesitate to contact us!
