Algae Control and Algae Removal in Lakes, Reservoirs and Ponds

14 Apr

When algae growth gets out of control in ponds, lakes, and reservoirs, this growth can be controlled and excess algae removed by reducing the amount of plant nutrients that are found in the specific body of water. Plant nutrients, or fertilizers, include phosphorus, nitrogen, a number of minor nutrients such as sulfur, as well as various micronutrients such as iron, manganese, zinc, magnesium, molybdenum and cobalt. Once these nutrients have been added to water they must go somewhere and will go towards supporting either weed or algae growth.

If an abundance of algae grows, the water will be shaded and weeds, which need sunlight, will be unable to grow. If the problem is excessive weed growth, the weeds will take up most of the plant nutrients in the water so the algae will be unable to grow. This is why algae removal using algaecides often results in excessive weed growth and, likewise, weed control using herbicides often results in heavy algal blooms. Lakes naturally shift every few years from having an abundance of weeds first, then an abundance of algae, or vice versa.

As you know, algaecides remove algae. Several sources have indicated that the use of excessive copper-based algaecides and alum can kill fish and other aquatic animals as well as interfere with the reproduction systems in fish. Copper compounds found in algaecides can kill beneficial bacteria in the lakes that typically feed on bottom organic sediment, or muck. Similarly, Alum can leave an aluminium hydroxide flocculent on the bottom of the lake that will interfere with both fish reproduction and beneficial bacteria and insects that feed on muck.

Copper compounds found in most algaecides can destroy water quality. As the dead algae decompose they not only release phosphorus and nitrogen, but also consume oxygen within the water. When there is a lack of oxygen in a water source, massive amounts of phosphorus and nitrogen from the sediment at the bottom is released into the water. When the oxygen level of water is reduced, fish kills often result. Copper compounds also add a new toxic sediment, known as copper carbonate, to the bottom, which interferes with both the bacterial decomposition of sediments and with fish reproduction.

If you remove all of the algae in a lake without eliminating the cause of the algae, the plant nutrients are still in the water and the algae will quickly return, unless weeds quickly take up the nutrients before the algae begins to grow again. When this happens, you will be left with a lake full of weeds. To control this delicate balance, the CLEAN-FLO Continuous Laminar Flow Inversion and Oxygenation System, in combination with our beneficial bacteria, Lake Clear or C-FLO-6 and Clean & Clear enzymes, will provide algae control by reducing carbon dioxide and available nutrients to such low levels that the algae removal occurs without a shift to an overgrowth of weeds.

Natural algae control is a result of nutrient reductions. The CLEAN-FLO Continuous Laminar Flow Inversion and Oxygenation System, in combination with our beneficial bacteria, Lake Clear or C-FLO-6 and Clean & Clear enzymes, will give algae control by reducing carbon dioxide and available nutrients to such low levels that the algae removal occurs.

Lake Clear - Lake Clear is a proprietary blend of bacteria specifically formulated for controlling nutrients that filamentous, blue-green and planktonic algae use for food

C-FLO-6- feeds on non-living organic matter and is particularly effective on reducing nutrients that are food for PLANKTONIC (suspended) algae.

Clean & ClearTM CONCENTRATED ENZYMES is a special blend of non-toxic vegetable enzymes from nature that acts as a catalyst to biodegrade non-living organic matter and reduces available nutrients in the water, thus improving water quality.
