When we face algae problems in our aquarium, it's important to understand that anti-algae products are only a temporary solution. In most cases, algae are due to a lack of balance or a deficiency of the necessary nutrients for our plants. To solve the root problem, we must address these imbalances or deficiencies. Only if no other solution has worked should you resort to the commercial liquid anti-algae for aquariums available on the market. These imbalances can also be caused by our turtles, which produce excessive waste, and if we don't perform proper maintenance, it can lead to problems with excess nitrates. In our post about aquatic turtles, we teach you everything you need to know to care for aquatic turtles.

When choosing an algaecide for aquariums, we must consider the base substance it is made from and the type of algae present in our tank. It is advisable to opt for recognized brands that have removed copper sulfate from their products.

Below, we present a group of products so you can choose the best option to buy aquarium anti-algae available on the market:

JBL Algol

JBL Algol is a product that helps control and prevent the excessive growth of algae in aquariums and tanks. Algae can be a common problem in aquariums and can be caused by a variety of factors, such as inadequate lighting, nutrient overload, poor filtration, among others.

JBL Algol is an effective treatment for the growth of unicellular algae, including green water algae. It is also useful for combating other types of outbreaks, such as brown algae. The product works by inhibiting photosynthesis and the reproduction of algae.

JBL Algol is not a permanent solution for algae growth in aquariums and tanks. It is necessary to identify and correct the underlying cause of the problem to prevent its recurrence. You must follow the product instructions and take safety precautions, such as ensuring that the oxygen level in the water is sufficient during treatment.

JBL Biotopol 250 ml
  • Para peces y plantas
  • Para acuarios de agua dulce y tortugas
  • Neutralización del cobre, el plomo y el zinc
  • Protección de la membrana mucosa

Dosage

The recommended dosage is 25 ml per 100 liters of water during the first week, and then reduce the dose to 12 ml per 100 liters in the second week. After 3 or 4 weeks, algae growth should decrease significantly.

Algae are expected to decrease in about 3 or 4 weeks.

Tetra Algumin

Tetra Algumin is an aquarium anti-algae product manufactured by the German company Tetra. This product is designed to eliminate unicellular and filamentous algae in aquariums containing shrimp and snails. In addition to combating algae, Tetra Algumin also helps remove excess nitrogen compounds from the aquarium water.

Dosage

The recommended dosage for Tetra Algumin is 25 ml per 100 liters of aquarium water in the first week, and then decrease the dose to 12 ml per 100 liters in the second week. It is recommended to do a 30% partial water change before using the product and to ensure there is a sufficient concentration of oxygen in the water by aerating it while using the product.

If necessary, you can repeat the application of Tetra Algumin after 5 days. For best results, follow the usage instructions and consider the specific needs of each aquarium.

Seachem Flourish Excel Anti-Algae

Flourish Excel is an anti-algae product that has earned a great reputation in the aquarium hobby.

What exactly is Flourish Excel and how does it work?

Flourish Excel is a product based on glutaraldehyde, an organic compound used as a preservative and disinfectant. In aquariums, it is used as a carbon source for aquatic plants. Aquatic plants need carbon dioxide (CO2) to perform photosynthesis, and Flourish Excel anti-algae provides an easy way to add carbon to an aquarium.

Seachem Flourish Excel - Bote de Carbono orgánico, 250 ml
  • Fuente de carbono orgánico biodisponible para el acuario plantado
  • Uso como alternativa o complemento a la inyección de CO2
  • Introduce intermedios fotosintéticos
  • Número de modelo: 020987

How does this help prevent algae growth?

Well, if aquatic plants do not have enough available CO2, they may struggle to grow and develop. This can make the plants weak and unable to compete with algae for nutrients in the water. By adding Flourish Excel to the aquarium, you provide an additional source of carbon for the plants, allowing them to grow stronger and healthier. This can help prevent the growth of unwanted algae.

Besides helping to prevent algae growth, Flourish Excel can also have other benefits for an aquarium. For example, some aquarists have reported that it has helped improve the health and growth of their aquatic plants, and it can also help reduce the amount of cyanobacteria in an aquarium.

Flourish Excel is not an anti-algae in the traditional sense. It does not directly kill algae, but helps prevent their growth by providing a healthier environment for aquatic plants. Therefore, you may need to use other methods to control algae growth in an aquarium.

Homemade aquarium anti-algae

The use of hydrogen peroxide as an anti-algae in the aquarium is a method commonly used by some aquarists, although you should be cautious when using it. Hydrogen peroxide can be effective in killing algae, but it can also be toxic to fish and other aquatic organisms if used excessively.

Dosage

Dilute the hydrogen peroxide solution. Mix a solution of hydrogen peroxide and aquarium water at a ratio of 10 ml of hydrogen peroxide per 100 L of aquarium, divided into two doses. For example, in a 50 L aquarium, you would do two doses of 2.5 ml, one at 8 in the morning and another at 8 at night.

This method can be effective for eliminating algae, but it can also kill beneficial bacteria and other organisms in the aquarium. Therefore, it is recommended to use this method with caution and not excessively. You should thoroughly research any homemade method before using it in your aquarium to ensure it is safe for your fish and other aquatic organisms.

What are algae?

Aquarium algae are photosynthetic organisms that grow in the aquarium water and on the surfaces of decorations, plants, and substrate. These algae are a natural component of the aquarium ecosystem and can be beneficial to the aquarium environment by providing oxygen and nutrients.

However, if they grow excessively, algae can cause problems in the aquarium, such as reducing water quality, making the aquarium look unsightly, and affecting the health of plants and fish. We must maintain a proper balance of nutrients, light, and CO2 in the aquarium to prevent excessive algae growth.

Types of algae

There are several types of algae that can grow in an aquarium. Below, I describe some of the most common types of algae:

Green algae

These are the most common algae and appear as green spots on the walls of the aquarium, decorations, and on the substrate. They can be caused by a variety of factors, including excess nutrients and light.

Brown algae

These algae appear as a brown layer on decorations and plant leaves in the aquarium. They usually appear in new aquariums and can be caused by a lack of light.

Filamentous algae

These algae appear as long filaments and can grow on plant leaves and decorations. They are caused by excess nutrients in the aquarium and inadequate lighting.

Blue-green algae

Often called "cyanobacteria," they appear as a blue-green layer on decorations and on the substrate. They are caused by excess nutrients and a lack of oxygen in the aquarium.

Some algae are normal in an aquarium and are not harmful to fish and plants. If algae grow excessively, they can cause problems and affect the health of the aquarium. Therefore, maintaining good aquarium hygiene, performing regular water changes, and providing adequate lighting are important to prevent excessive algae growth.

Where to buy anti-algae for aquariums?

There are several options for buying anti-algae for aquariums. Here are some suggestions:

  • Aquarium stores: You can look for specialized aquarium stores in your area and visit them to see if they have anti-algae products available. There, you will find a variety of products and can also get advice from the staff on which anti-algae would be best for your aquarium.
