Why good water can show yellow the clearest water pisciculture is worse?
Many novice fish farmers like that the color of the water in the aquarium is transparent and clear, and they think that the water can make the fish have a good view. In fact, this idea is not right. We all have this experience, that is, tropical fish bought from fish shops need to be placed in their own tank for half an hour and then put the fish into the tank. At this time, we can see that the color of the water from the fish shop is different from that in our own fish tank. There is no need to panic at this time, because old water has color. Generally good old water has some dark yellow, dark blue and other dark colors. As long as the water is bright, there is no problem with such water.
The color of the water in the aquarium is mainly caused by the soluble matter dissolved in water. Usually, the food we feed to tropical fish has a lot of color-increasing additives in it, and these artificial pigments can easily dissolve in the water and cause discoloration of the water body. Usually, we also add some medicine to prevent and cure diseases in the fish tank. Some of these agents are also pigmented, which will also discolor the water body. There will be a large number of nitrifying bacteria in the tank that does not change water for a long time, and the nitrifying bacteria will make the water body of the fish tank dark brown.
However, when the water body in the aquarium looks opaque or has white suspended matter, we should be vigilant. The reason for turbidity is generally that the solid feed is fed too much, and the fish is not eaten immediately and deposited at the bottom of the tank. After soaking for a long time, it will be decomposed into small particles and suspended in the water. At this time, we should increase the filtration so that these suspended impurities are removed. In addition, a large number of microorganisms such as ciliates can also cause pollution in the water, so we must add fungicides to kill these ciliates and make the water clear.
As long as the water body in the aquarium is not turbid, discoloration is a normal change, but if it is not controlled, the color of the water body will become darker and darker, affecting the ornamental effect. The solution to this problem is very simple, we can add activated carbon to the filter tank to increase the filtration effect, the general situation can be improved, if still not, we can increase the density of water exchange to solve the problem of water discoloration.
