Water retention and stormwater reservoirs serve a vital function in controlling flooding and preventing pollutants from reaching surrounding natural waterways. The runoff contains some blend of the following pollutants:
Biological & chemical algae controls
What to expect from a biological additives in an algae control program
Biological cultures help remove buildup of organics such as hydrocarbons and plant debris. With mixing and aeration, you should notice a reduction in sludge volumes and improved water clarity. The cultures are very effective in lagoons with the most eutrophic conditions. In degrading organic pollutants, you should start to see increased D.O. and lower odors. If the problem is not as much pollution and more algae blooms, you should notice lower copper sulfate or algaecide usage rates.
Overall, I don't see adding biological cultures as a single product fix for eutrophication or algae blooms. It is best to combine multiple technologies to achieve best control.
