Fish farming must change water regularly, if the water is not changed in time, it will lead to water quality aging, thus making it yellow. Generally, according to the degree of turbidity of water quality, it is decided to change once a week or once a half month. If you change water frequently, you should not change more every time. It is OK to change one fifth. If you do not change frequently, you should change one third every time.
Many people think that algae outbreak in fish tanks is green, but in fact it is not, because there are many kinds of algae, and if a large number of brown algae are bred, it will cause the water body to turn yellow. In view of this situation, the best solution is to raise aquatic plants, which will absorb the nutrients needed by algae, thus inhibiting their reproduction.
If the amount of feed is not controlled at ordinary times, there will be a lot of residual bait in the water, and the bait will also cause the water to turn yellow. And it is decomposed by microorganisms, but also produce ammonia nitrogen, if the nitrification system is not established, ammonia nitrogen will lead to fish poisoning, adverse to their health, so feeding must control the dosage.
If you want to make a scene in the fish tank, you usually choose to put some sinking wood, and the new sinking wood will certainly cause the water to turn yellow, no matter how you deal with it, it can't be changed, but this kind of yellow water is harmless to the fish, so don't worry too much. If you want to improve, you can boil the sunken wood you bought first, then soak it in cold water, and repeat it several times.
