Second, avoid sunlight. Practice has proved that natural light can make algae grow fastest, especially green moss will proliferate rapidly, so it is necessary to build a arbor or use newspapers to shade the sun. The cathode fluorescent lamp used for aquarium lighting will also lead to incomplete chromatography due to aging, which will lead to algae reproduction. If conditions permit, you can turn on the UV lamp (ultraviolet germicidal lamp) and irradiate 1~2 hours every day. If you are sunbathing, you can add another 2 hours, which is also very effective.
Generally speaking, the fish tank is closed due to too long illumination time, resulting in a large amount of chlorine in the water, and new water has not been replaced for a long time, or the replaced new water has not been precipitated in advance 12 hours. Cause algae in the fish tank to multiply, and cause the fish tank to turn light green.
The solution is to prescribe the right medicine. Keeping the fish tank away from the sun and using professional fish lamps can not only meet the growth needs of fish, aquatic plants and other organisms, but also prevent the fish tank from turning green too quickly. Then change the water in the aquarium regularly, clean the aquarium regularly, and install an effective filtration system to purify the water for a long time and keep the aquarium clean and clear.
In addition, you can mix some aquariums that eat algae, which can effectively remove algae from the fish tank and prevent algae from multiplying too fast. Moreover, breeders can regularly use some algaecides to effectively remove algae organisms. Of course, the use of algaecide should be based on the safety of aquatic organisms, and the dosage and time of use should be scientific, and it should not be used at will.
