Algae is a vital part of the aquatic ecosystem. It is an aquatic living organism that requires sunlight and nutrition to grow other plants likewise. Algae can grow and sprout exponentially. There are two types of ways through algae reproduce. One is vegetative propagation, and another is the production of spores.

Four types of algae are found in water bodies: Green algae, Flagellates, Diatoms, and Blue-green algae. Among these, the blue-green algae are toxic for other living organisms, including humans. Blue-green algae spread toxins into the water and harmful for the animals if they drink such contaminated water. Human skin is very allergic to this kind of algae. People often feel irritation and red rashes when they swim into the water body having blue-green algae.

Why do algae grow in Dams?

Algae require these four conditions to grow: Sunlight, High Nutrients, Warm temperature, and Water pH between 7 to 8. And the exciting thing is that all of these conditions are ubiquitous in dams and other same kinds of water bodies. The algae bloom can disturb and damage the aquatic organisms and deter the quality and nutrition of water from the dams. That is why it is vital to Remove Algae Dam.

3 Effective Ways To Remove Algae From Dams

  1. Manually Removal:

When you inspect algae blooms into a dam, you should first manually remove that algae. It sounds like hard work. But it is a primary step. However, it is not a permeant solution. You can get rid of algae for a short period. At that time, you can find the best way to Remove Algae Pond by limiting nutrition and sunlight.If you suspect blue-green algae, it is advisable to use alternative methods and restrict the water for use till the next 10-15 days, as the presence of blue-green algae will contaminate it.

  1. Modify Dam Construction:

Algae can rapidly spread in water under the sun. The reason being, the rate of photosynthesis increases in sunlight and helps algae to grow. So, it is advisable to make deep dams instead of shallow ones. Because the sunlight cannot penetrate to the bottom of the dam is deep. Thus, the possibility of algae in a deep dam is low.

  1. Treating with Chemicals:

Generally, ferric alum used for a preventive purpose; you can use this chemical to get rid of algae. Algae require phosphorus and nitrogen as same as other plants. Ferric alum eliminates phosphorus from water, and this stops the growth of algae. Apply about 50 grams of Ferric alum per 1000 liters of water. Place this chemical on a porous bag with the float.

Simazine, Calcium hypochlorite, and Cupric ide also used to kill algae from the water. However, it might be possible that some of these chemicals harmful to other aquatic animals. It would help if you were careful while using chemicals to kill algae.


Algae can contaminate water and damage aquatic animals. You should continuously monitor the water for the presence of algae and immediately restrict water from the use if you sense blue-green algae. The ways, as mentioned above, are well-effective to remove algae. Comment below if you are facing the problem of algae. We will reach you soon.
