Aeration, chemical/biological additives, and ultrasonic technology are frequently employed to prevent algal colonies. Although there are numerous treatment options available, they all have disadvantages. For instance, algaecides provide fast results but are detrimental to the entire aquatic ecosystem.
There are numerous methods for algae control and prevention, including herbicides, bacteria and microorganisms, chemicals, ultraviolet (UV) sterilisers, and other additives such as barley grain. Each has a slightly different approach to combating algae, and some may be more effective in certain situations or applications.
A water filter is the most effective method to remove algae from potable water. The required water filter will depend on the type of algae present. In the case of blue-green algae (cyanobacteria), which is a bacteria and not an algae, nanofiltration, ultrafiltration, or reverse osmosis are optimal.
Prevent the formation of harmful algal and cyanobacterial colonies.
On your farm, in your yard, and in your garden, use only the recommended amount of fertilizers. This will reduce nutrient runoff into adjacent water bodies. Nutrients in the water can accelerate the growth of algae and cyanobacteria.
