Control Green Algae and Cyanobacteria Blooms in Lakes, Reservoirs and PondsGreen algae bloom and cyanobacteria (blue green algae) bloom control can be accomplished by reducing plant nutrients (fertilizers). These include phosphorus and nitrogen, minor nutrients such as sulfur and various micronutrients such as iron, manganese, magnesium, zinc, molybdenum, cobalt, etc. This is why algae bloom control using algaecides often results in weed growth. Herbicides to kill lake weeds or pond weeds often result in heavy cyanobacteria and green algae blooms. The nutrients must go somewhere. They will go either into weeds or algae blooms. Algae blooms shade the water so weeds cannot grow. If the problem is excessive weed growth, the weeds take up the plant nutrients in the water so the algae blooms cannot appear. Lakes naturally shift every few years from weeds to algae blooms or from algae blooms to weeds. It all depends on what becomes established first in the season. As you know, algaecides remove algae. Several references indicate that both excessive copper algaecides and alum can kill fish and other aquatic animals or interfere with reproduction in fish. Copper compounds can kill beneficial bacteria in the lakes that want to feed on bottom organic muck. Alum can leave an aluminum hydroxide flocculent on the bottom that interferes with both fish reproduction and with beneficial bacteria and insects that feed on lake muck and pond muck (muck). Copper compounds can destroy water quality. As the dead algae decompose they not only release phosphorus and nitrogen, they also consume oxygen. Lack of oxygen causes a release of massive amounts of phosphorus and nitrogen from the sediment into the water. Reducing oxygen often causes fish kills. Algaecides do nothing to improve the health and growth of fish, nothing to reduce bottom organic sediment. Copper compounds also add a new toxic sediment to the bottom, copper carbonate, which also interferes with bacterial decomposition of sediments and interferes with fish reproduction. If you control algae blooms in a lake without eliminating the cause, the plant nutrients are still in the water. The algae bloom will quickly return, unless lake or pond weeds quickly take up the nutrients before the algae grow again. Then you have a lake or pond full of weeds. Natural algae bloom control is a result of nutrient reductions. The CLEAN-FLO Continuous Laminar Flow Inversion and Oxygenation System, in combination with our beneficial bacteria, C-FLO-6 or C-FLO-6F and Clean & Clear enzymes, will give algae control by reducing carbon dioxide and available nutrients to such low levels that the algae removal occurs.CASE STUDY: Cyanobacteria in reservoirs and lakes (Controlling Blue Green Algae Blooms).
