Algae, just like other plants, both terrestrial and aquatic, have their advantages and purposes, no matter how harmful they may be in the environment. Yes, too many algae in the water give the other animals and plant a big competition in regards to the nutrients found in the water.
Even then, algae have a significant role in the nutrient cycle and oxygen emission. To grow and thrive in the water, they use the sunlight into cellular tissue. They are then eaten by aquatic animals, then get extracted and grow again. Also, a significant portion of the planet’s oxygen comes from the ocean, and algae are responsible for more than half of it. Algae, like other plants, are also a significant consumer of carbon dioxide, then releasing oxygen back into the water.
That said, there are measures you should take for algae control. Things like reducing the amount of nitrogen going into the water, continually checking the growth of algae, and improve the bacterial response to the excess nitrogen present in the water.
Algae grow fast
If left for a few hours, algae will reproduce to mass quantities. Because of this, it can be harvested daily, which gives it the potential to produce a lot of biomass and biofuel. The biomass and biofuel they produce are more significant than that of other agricultural produce.
The base of the food chain
If you are looking to produce natural food to your pet fish and plants in your pond, algae can be the thing you are looking for. An algae is the base of all food chains in the water. This is because it only needs sunlight to grow and reproduce. It is then eaten by microscopic animals, which will then be food to fish and other sea creatures.
Minimize toxicity in the water
With a controlled amount of algae in your pond, it can yield great results. Algae have an essential presence in your pond because along with other microorganisms and other plant life, it can minimize the level of nitrogen and other harmful substances in the water that can also harm the aquatic life. Algae absorb nitrogen and convert it into other gases such as oxygen, which is suitable for your pet fish and plants in the pond.
Microalgal biomass can be converted into food, fuel, and feed
Microalgae are a rich source of protein and oil, making it an excellent source of biofuel. It can also be converted into animal feed in large quantities. Not only in animals, though, as it is also used for various medical experiments to advance the progress of human health. Not to mention that there are already a lot of food supplements that contain microalgae.
Algae can purify wastewater
Even in a dirty environment, like sewage, wastewater, and other industrial toxic waste, algae can still thrive. It also cleanses the waters, acting as a filter to the harmful substances present in the area. Also, it is still able to produce biomass, which can be used as biofuel, even in toxic environments.
If you are looking to make your plants safe and have a more natural environment, having controlled algae in your pond will yield great results.
As you know, nitrogen is a primary nutrient that plants need to thrive and go to the next phonological stage. Unlike other plant life, algae are the only aquatic plant that absorbs nitrogen and, upon dying, release nitrogen back in the water. This event is called Nitrogen Fixation.
Not only is it helpful in growing your pond plants, but it is also responsible for suppressing harmful bacteria and other toxic substances in the water. Because of this, fertilizer and other artificial products for plant growth are no longer needed.
Algae also consume Carbon Dioxide
Just like any other plant, algae can also absorb Carbon Dioxide. While also absorbing sunlight, it also uses Carbon Dioxide to grow and thrive. They then release oxygen in the water for the aquatic animals. Also, if you are living near a factory or an industrial plant, algae can help purify your water sources because it need a lot of Carbon Dioxide to thrive, which is found in industrial plant and factory emissions.
A lot of people believe that algae are a sign that your pond is slowly dying. Whenever it does, people despair and do everything to get rid of algae. However, the presence of algae in the water is not at all a bad thing.
Useful things like oxygen emission, the ability to do nitrogen fixation, and being a healthy food source for aquatic animals are just some of the things that could make your pond livelier. Algae are the base of the food cycle in the water, and without it, there is a big chance that your pet fish would not have their proper nutrients, as well as making the pond vulnerable to toxic substances.
