Cyanobacteria Why blue-green algae can be a serious risk to people, pets, fish and water quality Cyanobacteria, often called blue-green algae, are much more than an unattractive surface bloom.

For landowners, lake managers, fisheries, golf courses, councils and private pond owners, cyanobacteria should never be ignored. A

When extreme heat arrives, most pond owners worry about the water getting too warm. But the biggest danger to pond fish is often not the heat itself.

Freezing weather can be one of the most stressful times for a pond.
