This also provides nutrients for algae growth. If there is any suspicion of chemicals, such as biocides or others, find out how long since the last application. Ask if pesticides are used on the property or possibly on adjoining property which might find their way into the water. If the answer is yes, send a copy of the test results to Valerie or Claudia and allow our cumulative experience to guide your prescription. In many parts of the world, there is a cold season and a warm season.
Bacterial activity slows down in winter time.
It does take place, but at a slower pace. When treating lakes, ponds, and reservoirs, consider how much time is available for warm weather clean-up. To determine this, consider how long the water will be at least 50 degrees F. Surface water may be several degrees colder in the fall or winter than water at a depth of 3-5 feet, which is the water temperature to consider in your calculations. Maintenance treatments should continue throughout the algae season with slightly higher dosages after each heavy rain, when run-off may bring outside nutrients into the water. If you are not sure how to identify the aquatic weeds, plants and algae, see the University of Georgia, Extension Agriculture website.
