The Dangers of Green Overgrowth

Algae growth in lakes, ponds, and reservoirs is a common seasonal occurrence, often influenced by nutrient availability, temperature, and light exposure. When these conditions align, algae can accumulate rapidly, sometimes forming thick layers or blooms that dominate the water’s surface.

These accumulations can interfere with light penetration, limit dissolved oxygen, and alter the visual and functional characteristics of a water body. In some instances, blooms may shift from being seasonal to persistent, affecting aquatic habitats and recreational usability.

There are several types of algae that may appear under these conditions, each with distinct characteristics:

Green Algae

Commonly seen as surface mats or filamentous strands (Stringy or hair-like algae). They thrive in nutrient-rich water and are often visible during warmer months.

Blue Green Algae (cyanobacteria)

They are microscopic organisms that can form dense surface scums in still or slow-moving water. Under certain conditions, they may release compounds that affect water odor, clarity, or quality.

Diatoms

They tend to be more common in cooler water and may appear brownish in color. These algae are often part of early-season blooms and may settle along the bottom or attach to submerged surfaces.

Golden Algae

Can cause discoloration and, in some cases, affect aquatic life through naturally occurring compounds. These species are less common but may appear under specific environmental conditions.

Overgrowth is often tied to elevated nutrient levels, especially orthophosphate. Algae Armor is designed to bind with orthophosphate in the water column, forming insoluble particles that settle at the bottom and reduce bioavailability. This approach may assist in maintaining nutrient balance across seasons.
