Tips on algae control in lakes and ponds

Algae control in lakes and ponds is usually an ongoing process and is necessary to maintain the water quality and the health of the fish and other wildlife that rely on these ecosystems. If left alone and ignored, algae can quickly overwhelm these water bodies, which is why water treatment with some sort of algae remover is essential.

It’s important that you don’t confuse algae with weeds, because whilst they might appear similar in the water, they require different approaches for containment. Algae are single or multi-celled organisms that make energy using photosynthesis, but they don’t have roots, leaves or stems like plants and weeds. Sometimes duckweed is mistaken for floating algae and Stonewort algae for bottom hugging weeds, so it’s important to identify the cause of your problem, before initiating a water treatment plan.

Short term solutions for algae control in lakes and dams

If you have just noticed an abundance of algae in your lake or dam and it looks like pea soup or the bottom is covered in string algae, you can use a chemical algae remover to hit the problem quickly. The issue with a chemical water treatment however, is that it will kill goldfish and Koi, and trout can also be affected if the carbonate content is less than 50 ppm. If you can’t use a chemical solution, then you need to look at long term control immediately.

Long term solutions for algae control in lakes and dams

A chemical algae remover is a short term solution to a crisis situation, but you need to move on from here and initiate a longer term approach to controlling the algae issue. The easiest and most successful long term plan is to tackle the overload of nutrients that feed the algae, creating the population explosion you have just attacked with chemicals.

Nutrients usually come from runoff and can be difficult to control on the land, so you need to tackle the problem another way. One of the most beneficial solutions is to make sure that you maintain a decent size fertilizer buffer around the lake or dam, so that runoff is less likely. Then install an aerator in the water to keep oxygen levels high and reduce the build-up of organic debris on the bottom.
