Q: When should I stop treating algae?
Rich – Bartlesville, OK
A: It’s not so much a matter of when as it is what temperature your water is.
In theory, with the right equipment, algae can be managed all year-long. But if you want to treat it with chemicals, the water temperature in your lake needs to above 60 degrees Fahrenheit. The active ingredients in Pond Logic® Algae Defense® that are used to control suspended, floating and bottom-of-the-pond algae require warmer water temperatures to work properly.
So when your water temperature is below 60°F, you’re out of luck for using chemical treatments.
Before cooler temperatures chill your water this fall, give any planktonic algae, filamentous algae or chara growing in your pond a dose of Algae Defense®. The best time to apply the fast-acting formula is in the morning on a calm, sunny day. Simply mix with water and spray directly onto algae with a pressurized sprayer. Once the green stuff is dead, don’t forget to remove it with the Pond & Beach Rake to prevent an accumulation of dead algae and muck.
So what do you do if you’re hosting a Halloween party but the water temperature in your pond—filled with spooky, pea green masses—is lower than 60°F? Try clearing things up with The Pond Guy® PondSkim™. Measuring 5 feet wide and constructed with a super tough screen, the skimmer floats on the water surface and collects floating algae as you pull it along with your boat. Problem solved!
