The algae in the aquarium grow very fast, and it is very laborious to clean up each time. Too many algae are difficult to take care of, affects the ornamental effect, and is not good for the health of the fish. So what is the reason for the algae burst in the fish tank? The causes of algae are mostly too rich water and too much light.
Causes of Algae Burst in Fish Tanks
The advantage of family fish keeping is that it is highly ornamental and pleasing to the eyes, but water quality is a big problem, and the problem of algae in the fish tank is a long-term problem for fishers. Too many algae are not only difficult to take care of, affects the ornamental effect, and is not good for the health of the fish.
The causes of algae are mostly too rich water and too much light.
Excessive feed, bait, and pulled fish in the fish tank can become harmful substances in the fish tank. Feed and bait contain a large amount of protein. Nitrate and ammonia nitrogen produced by fish decomposition are all needed for algae growth, which will accelerate the algae reproduction in the fish tank.
Under normal light, a few algae will grow, which is basically harmless to the fish. As long as the tank wall is scrubbed frequently, this will not happen. Once the light time is too long or strong light, it will promote the metabolism of algae, accelerate the growth rate of algae, and endanger the health of the fish.
How to Avoid Algae Growing Algae
1. Reduce direct sunlight to water
It is recommended not to place the fish tank on the balcony, rooftop, etc., to try to avoid direct sunlight on the fish tank.
2. Treatment of brown algae with germicidal lamp
The germicidal lamp can effectively remove green algae and brown algae in the water, but this is when the algae have not grown to a particularly large amount.
3. Put in tool fish such as queen, dark beauty, scavenger, etc.
Not all tool fishes are effective, and tool fishes are in danger of being eaten by large fish in the tank. The premise of putting tool fish is not feeding them, because many tool fish do not work when there is fish food.
4. Wipe the tank often
For algae, like green algae easy to be wiped, they are often one wipe away. This is also related to personal diligence. Some people think this is a big project.
5. Regular water change
So for all algae, changing water is the best way. If there are algae, you can increase the frequency of water changes appropriately. For example, it was changed only once a week or half a month. It can be changed every 3 days. The amount of water change is controlled within 1/4 of the entire tank water. However, too much water change will affect water quality and affect living creatures.

6. Adding drug
For green algae and other harmless algae, it is easy to be removed and can be cleaned by wiping the tank, but for stubborn and harmful algae such as brown algae, black hair algae, membrane algae, it should be removed as early as possible. These harmful algae are a hindrance to the ornamental value of fish tanks and the development of nutrients in the water, as well as the healthy growth of fish. The use of various dephosphorization agents and dealgal agents can greatly reduce the number of algae in the tank.
Algae Removal Methods Commonly Used in Aquariums
Commonly used algae removal methods are divided into physical, chemical, and biological.
1. Physical algae removal method
In simple terms, physical algae removal is to use manpower to remove the flooded algae by yourself. There are special brushes for selling aquariums on the market, which is very convenient. Combined with a water change, it can have a good algae removal effect. It is a bit cumbersome to implement and some corners are not easy to brush. Of course, if even the aquatic plants, sand, and other decorations aquarium are unfortunately caught by the algae, at this time, in addition to the pain, they must be taken out one by one and brushed patiently, and then disinfected with brine. The algae on the water grass branches and leaves can only be trimmed one by one, and aquatic organisms that eat algae are added.
2. Chemical algae removal method
Some of the algae-specific algae removal agents are effective for almost any algae in the aquarium, and where physical algae removal is not easy to remove, the agents can also penetrate in and destroy the algae. But because it is a chemical, it has a certain impact on the ecological balance system in the fish and the aquarium. It should be noted that the use of chemical agents must strictly control the dosage and follow the dosage on the instructions. If it is not handled properly and the dose is too large, it will not only kill algae but also damage fish and water plants.
3. Biological algae removal method
Add some aquatic life that can eat algae to control the number of algae. Compared with the first two methods, the effect time is slightly slower, but it is safer and labor-saving. It is a very environmentally friendly method. We have aquarium accessories online, welcome to buy.
