Pond & Lake Q & A
Q: I see some algae in my pond. Is it too cold to treat my pond at this point? – Jack of Ohio
A: Algae has a tendency to grow in colder temperatures even when there is ice covering your pond. To treat or not to treat really all just comes down to the temperature of the water. Algaecides, like Algae Defense (or Hydrothol if your have koi or goldfish in your pond), are most effective when water temperatures are above 50-60 degrees Fahrenheit. If you are living in the southern climates, the water temperatures may be already high enough for an algae treatment. As for the northern climates, it may be best to hold off until the water temperatures rise above the 50-60 degree Fahrenheit threshold.
