My pond has some filamentous algae growth around the edges. It’s too cold to treat, right? | Ponds & Lakes Q&A

A: Cold-weather algae. It’s the worst. And, unfortunately, you can’t treat it right now because the temperatures are too low. Your pond or lake’s water temps need to be higher than 60°F before you can start treating the green stuff with algaecide.

So until things heat up, you have two options:

  1. Rake It Out: If you can safely access and maneuver around your pond, grab your Pond & Beach Rake and get to work skimming and pulling that filamentous algae out of the water and up onshore.
  2. Add Some Color: Pond Dye will limit the amount of sunshine that reaches the algae. Without enough sun, the algae can’t survive. So toss a Pond Dye water-soluble packet or some liquid concentrate into your pond – and your problem is solved!

Once your water temperatures rise above 50°F, start adding PondClear™ & MuckAway™ to the pond. The beneficial bacteria will clear the water and start breaking down the debris and nutrients that are feeding that troublesome algae.

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!
