How long will the blue-green algae be here for?
• Blue-green algae are a natural part of the environment. A very small quantity of blue-green algae is present all the time, but when the weather patterns are right for them to grow they can multiply into potentially harmful numbers (commonly known as a ‘bloom’), and there is very little that can be done to stop them. It is difficult to estimate when blooms will occur and when they will die off, although numbers tend to increase during summer and high temperatures, and decrease during the winter.
