Dennerle AntiAlgae direct* provides a swift and simple means of killing off irksome thread algae, which tend to grow around the edge of the pond or float at large mats on the surface of the water. The powder is sprinkled directly onto the algae. The active oxygen which is released destroys the algae cells. The dead algae are broken down by the bacteria living in the pond. The active component hydrogen peroxide quickly decomposes completely into oxygen and water.

Manufacturer's Description

Algae are a natural component in every body of water, including garden ponds.

As one of the  most important links in the food chain, they form the basis of life for many organisms which inhabit garden ponds. Algae become a nuisance when they multiply too rapidly in an uncontrolled manner, however: As suspended algae they colour the water green, as thread algae they form dense beds. Blooming algae is usually caused by an oversupply of nutrients in conjunction with intense sunlight. An oversupply of nutrients arises as a result of too much food and too many fish, or in case of inadequate nutrient consumption (insufficient water changing, too few pond plants).

The right care prevents algae from becoming a problem in garden ponds. Dennerle offers effective products to prevent algae - and should the worst come to the worst, Dennerle also offers fast-acting solutions to eradicate algae infestations.
