Harmful Algae Blooms (HABs)

Algae in freshwater Florida lakes can make the water green and slimy. However, they are essential to the ecosystem, providing food for all types of animals including fish, insects, mollusks, zooplankton (microscopic animals), and humans. Algae occur naturally in all types of systems and are indicators of an ecosystem’s condition, including the amount and type of nutrients that run through the system.

Most algae are not harmful but any type can grow out of control under the right conditions and the blooms of some types of algae can be detrimental to the environment, plants, or animals. A few species release toxins that are hazardous to animals and humans.

Cyanobacteria is a type of blue-green algae which can exist in low nutrient to very high nutrient environments and is the most common form of toxic algae in Florida lakes. Cyanobacterial toxins cause skin irritation on contact, or more severe reactions if the water is ingested. In addition to the identification of problem algae, toxin testing is also available.

Microcystis is another type of blue-green algae. Some strains of Microcystis have the ability to produce a toxin known as microcystin which is potentially harmful when in abundance.

There are many factors that can cause the overgrowth in your lake. The professional staff at Aquatic Systems will do a thorough evaluation to determine the root causes before we recommend ways to control it.
