the yellow water in the fish tank? If there is yellow water in the fish tank, you need to change the water immediately. At the same time, you should strengthen the filtration and pay attention to changing the feed. If there is sunken wood, you should also fish it out. There are many cases of yellow water, but most of them are caused by some impurities in the water, so we can put some filter materials with adsorption capacity in the water, such as activated carbon, which can effectively improve the phenomenon of yellow water in only 2-3 days.
1, sunken wood yellow water: untreated sunken wood directly into the fish tank, will cause the fish tank water yellow. This kind of yellow water is not harmful to fish, but it does not look very beautiful. If you want to solve this problem, you can put the sunken wood into the pot and boil it several times, so that when you put it into the fish tank, there will be no more yellow water.
2. Pigment feed: If pigmented feed is used to feed fish at ordinary times, the fading of feed will also lead to yellowing of the water body. This situation is easy to occur when raising some colored fish, which need to change the feed in time, or reduce the amount of feeding, extend the feeding time, so that the fish can digest.
3. Aging of water quality: If the water is not changed for a long time, it will lead to aging of water quality, and the old water will turn yellow easily. It should be noted that this kind of water often has high ammonia nitrogen content, which is harmful to the health of fish, so it is necessary to change the water every once in a while, usually about a quarter of each time, do not change too much.
