Algaecides for Ponds & Lakes

How Do Pond Algae Killers Work?

Fast-acting and easy to apply, pond algaecides contain chemicals that target and disrupt the cellular structure of various types of algae, causing them to die off. The best pond algae remover will depend on the type of algae you’re dealing with, and application recommendations will vary depending on the time of year. For example, if you have fish and the weather is warm, it’s best to treat your pond piece by piece with 10-14 days between treatments to reduce the likelihood of fish loss due to oxygen depletion.

Algae killers for ponds and lakes come in two forms – granular and liquid. The Pond Guy's granular formulas are comprised of powder or pellets that must be applied to the affected area with a hand spreader to ensure even distribution, while liquid algaecide for ponds and lakes can be sprayed directly on the weeds you're targeting.
