Whether you are looking for a preventive or destructive (curative) treatment, our algaecides keep your water clear and healthy all season long. Delivery throughout Quebec and Canada.
Preventive or destructive algaecide?
Preventive algaecide is used regularly to prevent algae from appearing; destructive algaecide (curative), more concentrated, eliminates existing green water. The higher the percentage (40% or 60%), the more powerful the action.

How to use an algaecide?
First, maintain a balanced pH and chlorine level, perform a shock treatment if the water is green, then add the algaecide according to the indicated dosage (depending on the water volume) with the pump running. Regular preventive use prevents most algae problems.

Frequently asked questions about algaecides
Preventive or destructive: which one to choose?
Use a preventive for regular maintenance to avoid algae, and a destructive (40% or 60%) when the water is already green or cloudy.
My water is green, what should I do?
Balance the pH, perform a shock treatment, add a destructive algaecide, run the filter continuously, and brush the walls. Repeat as needed.
What is the difference between 40% and 60%?
The percentage indicates the concentration of the active ingredient: a 60% is more powerful and is used in smaller quantities than a 40%. Always follow the dosage on the label.
Does algaecide work against mustard and black algae?
Mustard and black algae are more tenacious and often require a specialized algaecide, reinforced shock treatment, and vigorous brushing. Ask us for advice on the right product.
