1, manual removal method

After algae multiply in large numbers, the most direct removal method is manual removal. Appropriate tools can be used to remove the attached algae, such as using a glass brush or toothbrush to remove the attached algae on the glass wall or equipment. If algae are attached to the leaves of aquatic plants, the leaves can be directly cut off.

2. Chemical removal method

There are many algaecide drugs on the market, which can also be used to kill algae, but most algaecide drugs are harmful to aquatic plants, even to fish and shrimp, so we try not to use drugs. If you really need to use drugs, you can use low concentration to kill algae, with the least damage to aquatic plants.

3, stocking algae-eating biological method

Some fish can eat algae attached to the aquarium wall, such as lichen rats. We can use this feature to eliminate algae in the aquarium. There are also some shrimps and snails that can eat algae, such as giant shrimps and black shelled shrimps, which can eat most algae in a short time; Ampullaria canaliculata can also eat epiphytic algae in aquatic plant tanks instead of aquatic plants. These fish, shrimp and snails are also ornamental and can be matched according to the actual species of fish and shrimp.

4, ultraviolet killing algae

Using ultraviolet germicidal lamp (UV lamp) can kill algae and algae spores at the same time. If there is phytoplankton in the water, it can be killed by ultraviolet circulating germicidal lamp. Ultraviolet irradiation on the place where algae are attached can also kill algae within a few days, but it will have a certain impact on aquatic plants.

The methods of preventing algae in fish tanks can refer to the following points:

1, don't put the fish tank in the sun.

Remember, don't put the fish tank in a sunny place, which is a good condition for the growth of aquatic organisms, and it will provide algae with too much metabolic energy and consume a lot of water and nutrition, which will soon lead to the imbalance of aquatic plants and inhibit their growth, so that algae will have an advantage.

2. Prevention

Before planting aquatic plants, it is necessary to add some moss removal elements to the water. In addition, when buying aquatic plants, we should first look at whether there are algae on the surface of aquatic plants, and once found, we should abandon them. If you say you bought it home, it is recommended to gently wipe it on the surface with your hands, and then soak it in 50% moss remover for about 3-4 hours after cleaning.

Step 3 prune aquatic plants

In view of the broken branches and leaves of aquatic plants, it is necessary to trim them in time, and the glass on the inner wall of the tank should be cleaned at ordinary times, so that algae can not settle on the glass. In addition, a certain amount of water flow should be ensured in the fish tank, which can also ensure the cleanliness of the leaves of aquatic plants.

4. Daily observation

Tip: Develop a good habit of observing every day. Once algae is found in the fish tank, some measures need to be taken in time. In particular, spotted algae and filamentous algae should be removed immediately when they appear at the bottom or root of aquatic plants or extend to the edge of leaves.

5. Change water regularly

Changing the water in the fish tank regularly and quantitatively is also a measure to remove and inhibit algae production. Experienced people suggest that it is more appropriate to change water once a week, one third at a time.
