5 Tips on How To Get Rid of Algae Bloom In Aquarium

You have set up your new aquarium, and everything seems to be quite well. Your fishes are happy and active, and the aquarium adds enough charm to your room.

Then you notice that the aquarium water has a weird green hue to it, which makes sense. At first glance, it seems to be normal. However, this may not be the scene.

Tips on How To Get Rid of Algae Bloom In Aquarium

When a bloom starts to cloud the water, a competent aquarium owner must know how to stop this spread.

Now, the question is how to get rid of Algae Bloom in Aquarium? Let us read in detail about the problem and solution.

1. Establish a fine-fiber filter floss media system.

This process makes use of a fine filter media for straining the aquarium’s water to a greater extent than compared to your normal filtration system. As per experts, this process is highly effective whether you use it alone or along with other approaches. 

However, remember that this process may not be efficient enough if there is free-floating algae in the aquarium. 

It does an awesome job of making hazy water look clean. However, the green tinge will be there as long as the flower is in bloom.

In order to use the filter media effectively, insert it someplace in your filter and make sure to change it on a regular basis. When it comes to capturing microscopic particles, using the correct filter floss will be pretty effective.

Although it has its limitations, it plays a role in aquarium maintenance, particularly as a low-cost alternative to a permanent sanitizer while the aquarium is being renovated. This is a perfect solution to how to get rid of Algae Bloom in the aquarium.

2. Reduce the amount of blue light emission by your aquarium lighting fixture.

As per experts, another effective method may be to reduce the blue light spectrum emission by your aquarium lights. You can do this by replacing the light you have been using.

One method may be making use of an LED system that focuses mainly on the red spectrum of light.

However, if you are already using an LED system for your aquarium lighting but do not offer a programmable spectrum, it may be time to consider replacing it with a better one.

Removing the actinic blue light from your LED lights’ schedule completely may make a significant difference in the clarity of the murky green water in your fish tank.

3. Keep Nitrate levels under control.

Identifying and addressing the core cause of what seems to be a never-ending algal bloom is essential if you want to avoid further damage to your water quality. Algae needs food to exist, and this food is provided by high Nitrate levels in the water, caused by decaying fish food and waste.

An overcrowded tank will need more care and cleaning to guarantee that no green micro-algae take over. Because fish waste creates organic compounds like ammonia, which is turned to nitrate by nitrifying bacteria in your tank, and algae greatly adore nitrate, this is a good thing for you.

4. Incorporate an aerator into your aquarium.

You may want to consider adding an aerator to your aquarium to facilitate the operations described in my last piece. Well, this is not a straight remedy for getting rid of green water in your aquarium but rather a preventative technique to use while the ecosystem’s equilibrium is being restored.

Both of these bacteria need a large quantity of oxygen in the water for survival. When there is a bacterial and algal bloom, the demand for oxygen increases. Your fish are fighting with the microflora and fauna in the water, detrimental to their health. During the nighttime hours, this impact is amplified.

During the day, plants and algae create oxygen, which they use to convert energy into carbohydrates. However, during the night, a process known as respiration takes place, which uses the carbohydrates in the bloodstream as cell nourishment.

It is possible to think about respiration as the polar opposite of photosynthesis. The process of converting carbohydrates into cell energy depletes the body’s oxygen supply. 

5. Remove any contaminants from the substrate.

Over time, the substrate at the bottom of your tank develops into a self-contained ecosystem of its own. This is typical; but, if overfeeding or overcrowding were a problem, the heterotrophic bacteria found in this ecosystem dwelling inside the aquarium’s bottom might have populated the tank.

Continuously recurrent algal blooms and chronic green water may be produced by pockets of heterotrophic bacteria still growing in the nutrient-dense substrate at the bottom of your aquarium, which may be highly dangerous to your fish.

List of Causes of Algae Bloom in Aquarium In 2022

When you encounter green water for the first time, it might not be comforting. It is necessary to understand the root cause of the problem to be successful in tackling it.

Aqueous micro-algae spores, also known as phytoplankton, are always present in an aquarium, although they may bloom and cause the water to become hazy and green in color. The presence of an excessive amount of organic nutrients in the water column is typically the cause of an algal bloom. Reduced availability of nutrients in the water may help to reduce the color and clean the water.

These algal blooms survive on the same nutrients and conditions as any other plant. The essential things in this situation are light and nourishment. It is when one of these elements is overabundant in your aquarium that green water becomes a concern.


These approaches should be effective in dealing with almost any severe algae bloom scenario you may encounter. They should also leave you in a better position to avoid algae blooms in the future.

Following this instruction to the letter will allow you to get rid of unattractive green water problems in your aquarium, as well as, in general, create a healthier habitat for your fish and plants to thrive in.

It would be best if you kept in mind that algae are constantly there in the environment. Still, with the appropriate balance of nutrients in your tank and the necessary equipment to get rid of blooms when they come, they may live in peace for the rest of your life.
