5 TIPS FOR TREATING POND & LAKE ALGAE

CharaString Algae

 

  1. Treat Only Actively Growing Algae

    When using algae control products in a pond or lake, the algae must be present and actively growing. Why? Because the chemicals need to make direct contact with the tiny organisms and absorb into their cells for them to be effective; if there’s no living algae, the chemicals will land in the water and become diluted, and therefore ineffective.

  2. Treat When Weather Is Favorable

    Algae can grow in cold temperatures – even frigid, depending on the species – but algaecides aren’t so tolerant. The pond water must be warmer than 60°F for the chemicals to work. Apply algae treatment on a sunny, mild day when rain is not expected in the immediate forecast. This will allow the chemicals to adequately absorb into the algae. As always, read the product label for instructions and specific temperature requirements.

  3. Treat Only a Third at a Time

    When temperatures heat up and the algae dies off, that combination of warm water and decaying plant matter reduces the amount of oxygen available to fish and other living critters in the pond. Keep them in an oxygen-rich environment by treating the pond in small sections and wait 7-10 days before moving to the next section. In addition, keep an aeration system or fountain running during treatment to continue circulating and oxygenating the water.

  4. Read the Product Label

    Different algaecides have different active ingredients, inert ingredients and specifications, so always read your product’s label for appropriate protective equipment and application rates. Pay special attention to warnings concerning water use and restrictions in ponds used for irrigation, drinking and swimming, as well as in ponds that house certain types of fish such as Trout.

  5. Follow Up with Airmax® Ecosystem Pond Management Program

    Algaecides are a great tool that can temporarily clear up pea soup water, but they do little address the actual problem causing the algae – which is excessive nutrients and organics. By following up with proactive pond management practices, such as aeration and natural water treatments like MuckAway , you will reduce the accumulation of dead organic material, which will help to keep water clear season after season.
