Algae control refers to the management of algae growth in water environments and systems to maintain water quality, ecological balance, and visual appeal. Algae are photosynthetic organisms found in natural waters as well as in man-made settings such as ponds, aquariums, fountains, swimming pools, and irrigation channels. When conditions such as excess nutrients, warm temperatures, abundant light, and still water persist, algae can bloom, leading to discolored water, odor, reduced oxygen levels, and potential harm to aquatic life and water use.

Control strategies fall into preventive, cultural, mechanical, and chemical approaches. Preventive measures focus on limiting nutrient inputs, such as reducing fertilizer runoff, improving watershed management, and promoting nutrient uptake by plants. Cultural methods include managing light exposure, maintaining appropriate flow and aeration, and selecting compatible plant and animal communities to outcompete algae. Mechanical control involves physical removal of algae, routine cleaning of filtration systems, and improving circulation to disrupt stagnation. Chemical control uses algaecides or algistats, including copper- or chlorine-based products, hydrogen peroxide, and other approved compounds; selection depends on the environment, algae type, and safety considerations. Chemical methods require strict adherence to product labels and local regulations to protect non-target organisms and human health.

Integrated algae management combines these methods with ongoing monitoring of water quality indicators such as nutrient levels, temperature, light, and chlorophyll or turbidity measurements. In natural ecosystems, excessive intervention can disrupt beneficial microbes and ecological balance, while in managed systems, careful planning aims to minimize environmental impact and prevent harmful blooms, including cyanobacteria that may produce toxins.
