Variants of Algae in Aquariums

There are many types of algae, but we are discussing the six major ones present in a fish tank. Before you start worrying, identify the types of algae and see if it is harmful.

  1. Green Spot Algae: Green spot algae is a rare type and can grow on decorative items, aquarium walls, and aquarium plants, among other things. Green spot algae first appear as tiny spots; if not removed, it covers the whole thing. Green spot algae are often grown in new fish tanks with insufficient nutrients because healthy bacteria do not develop in such fish tanks. To get rid of green spot algae, change the water flow regularly and check the nutrient level of the fish tank.
  2. Black Beard Algae: This type of algae is also known as brush algae and is one of the most common. Black beard algae (brush algae) usually grows in saltwater aquariums but is sometimes also found in freshwater aquariums. Black beard algae grow very fast and are also challenging to remove due to their beard-like features. Its characteristics are that it is slippery and soft. To avoid beard algae (brush algae) in your fish tank, keep a close eye on it and clean the beard algae as soon as it starts appearing at first glance. You must provide proper lighting and stable carbon dioxide (CO2) levels for this.
  3. Blue Green Algae: Blue-green algae belong to the family of bacteria rather than plants. Blue-green algae invasion can get pretty disgusting, leaving a nasty smell behind. It also removes all the good and valuable nutrients from the fish tank. Blue-green algae appear in aquariums because of overfeeding, which leaves extra organic residuals in fish tanks. It is also caused by a lot of exposure to light and late water changes. To avoid the growth of blue-green algae, you can choose a blackout method and provide no light to the aquarium or place fast-growing plants inside the fish tank to balance the nitrate levels.
  4. Brown Algae: These algae can grow in saltwater and freshwater aquariums. They are slimy and can cover the aquarium walls with slime, algae, and film. It occurs if the lightning is weak or the oxygen level is low. It can be removed easily, unlike other algae growth. You can change the water frequently to lower the chances of growing brown algae and balance the light provided to your aquariums.
  5. Hair Algae (Filamentous Algae): Hair algae is a type of filamentous algae - a form of green algae that leaves long, loose threads on plants and gravel. When you touch hair algae, it feels like hair. It grows in the fish tank due to low nitrate and oxygen levels. It is challenging to remove hair algae, but algae-eating fish can be the best solution.

Ways to eliminate and prevent algae from aquariums without an algae remover:

  1. Control the Light: There is a considerable possibility of algae growth in an aquarium. It is advised to place the aquarium in less light to mitigate the procedure of photosynthesis and algae growth and production in fish tanks.
  2. Place Aquarium Plants: If you place live or aquarium plants inside your fish tank, the planted aquarium will consume the valuable nutrients that algae consume. Live plant growth will also provide a natural habitat for your aquarium pets and eliminate algae from the tank.
  3. Add Algae Eating Fishes and Invertebrates: Some fish and other invertebrates eat algae and consider it their food; hence, they are called algae-eating fish. Some algae-eating invertebrates are Chinese algae eaters, whiptail catfish, cherry shrimp, and others. The most common type of algae-eating fish is the Chinese algae eater. Chinese algae eater is placed in a freshwater aquarium, requiring clean water to stay active and alive.
  4. Manage Nutrients: Most of the time, algae growth happens due to high levels of nutrients in the fish tank. It occurs due to the excess fish feeding of imbalances of phosphates and nitrates in tap water.

Why do you need the algae remover for the aquarium?

An excess of nutrients in the aquarium water frequently leads to unwanted algae growth. Inadequate water plant growth and poor or improper lighting are other causes of algae growth in aquariums. That is why removing algae is essential and is a significant step towards a clean and algae-free fish tank. An algae remover makes it easy to remove the algae, which can otherwise be very challenging.

The aquarium gives a nice aesthetic view until algae growth comes in. This stubborn alga is often challenging to remove. Algae growth also negatively affects the overall fish habitat. Every aquarium keeper occasionally has to deal with aquarium algae, but with the correct tools, you can fight all the stubborn algae, which is pretty challenging to clean. Although algae is a natural organism, at the same time, it can turn out to be inconvenient for aquatic plants, aquarium ecosystems, and fish tank owners.

Many alternatives are available to keep the aquarium algae-free, but using an algae remover or algaecide is also a great option. Algaecides are available in a range of sizes, shapes, and brands. In addition, they come in different variants like; blocks, tablets, liquids, or powders. Despite their appearance, algae removers have a common objective: eliminating the algae. It is done by wrecking the algae growth or suffocating the same existing algae. Before buying the algae remover to clean tough algae, understand your freshwater or saltwater fish tank, aquarium plants, plant growth, and aquarium water.
