Algae in ponds and lakes can be a nuisance. Proper pond management will help avoid algae growth. Aeration and filtration and circulation assist in reducing the conditions favorable to algae. Algaecides can be used for algae control. Barley straw and microbial products can also be effective tools in maintaining clear waters. Dyes are also useful in reducing sunlight and manual removal is also a good practice prior to treating ponds with algaecides or herbicides. We offer a wide variety of chemical and natural products to control algae in watergardens ponds and lakes.
