Yes, it is beneficial for the fish tank, if the quantity is small. There are many benefits of algae, as it filters harmful chemical substances from water and keeps the nitrogen cycle maintained, and also provides oxygen. It also gives a natural look to the aquarium.

It is also bad to some extent because once it gets more in quantity it makes really it very hard to get rid of. They get multiplies very fast and it also blocks lights from reaching other aquatic plants which later results in death. Excess algae are also harmful to our colorful companions.

 

How to get rid of algae?

We have to follow a certain parameter to control the excess growth of the Algae plants. The ways to get rid of algae are as follows:
  1. We can grow more aquatic plants that will create competition between more growth for nutrition and that will reduce the algae growth.
  2. Lower the intensity of light will reduce the photoperiod and hence it minimizes the growth.
  3. Do not overfeed because that creates nutritive waste and leads to the growth of algae.
  4. Do regular maintenance like changing the water and cleaning the substrate. Also, improve the filtration system or clean it on time.

If there is already an excessive amount of algae in your tank then you can use the artificial algae remover which is available in your near store at very affordable prices.

What are the types of algae found in aquariums?

In a fish store, you have probably seen many types of algae related to the landscaping inside a fish tank respectively. If you want to add an algae eater to your tank, then it’s going to depend on the type of algae in that fish tank. The types of algae are as follows:

 

Blue-green algae

Blue-green algae

These algae are also known as cyanobacteria, it grows well in place that has high nutritious level with low nitrites compounds, such as substrate where the waste residue is present and filters in the fish tank. In some cases gives a reddish appearance, and has very rapid growth characteristics.

 

Green algae

Green algae

Green algae are very common blossoms in a tank if the lighting will be long and bright or the cycle of the fish tank breaks.

 

Green-spot algae

Green-spot algae

These are also similar to the green algae but it is very hard to remove and their favorable condition is low CO₂ and phosphate level. The name spot is given due to its characteristics, it grows like spots on the glass of a fish tank.

 

Green-hair algae

Green-hair algae

The name itself shows that it’s a hair-like structure and can grow more than an inch. The favorable conditions are the same as the green spot algae. It grows very rapidly in a wispy filament throughout the surface of the tank.

 

Brown algae

Brown algae

These brown-colored algae generally grow up in a new tank, if there is low lightning and an unbalanced routine of cleaning. If the water is having a moderate level of nitrates and phosphates, then it can grow at any substrates present in the tank even including the glass wall.

 

Brush algae

Brown algae

These are not common but are generally found inside the filters and on the slow-growing plant. A low level of carbon dioxide inside the tank is most favorable for these types of algae.

These are the fish tank algae generally found in their suitable conditions. If the water circulation is poor then we can notice that black-colored algae started to grow on the bottom surfaces.

In some cases, we notice that fish tank water is slowly turning out green color. This indicates that due to overfeeding the level of ammonia in the fish tank increases which seemss like green algae water.

  • Tank size matters to the algae eater, the one of smaller size can live in 10 gallons but another hand the bigger size can be up to 12-15 cm which needs at least double of the first one i.e. 20 gallons in the tank. 
  • The speed of the current in water is not the same for every algae eater, some of them are adapted to fast and for others, it can be stressful.
  • The companion or mates we choose matter because they can be aggressive or their behavioral changes cause stress to them.
