fish pond, it means that the water is too fertile and the nitrification system of the water body is not good enough, so it is necessary to cultivate nitrifying bacteria. This is a kind of aerobic bacteria, which can convert ammonia nitrogen into nitrite and nitrite into nitrate, so that fish will not be poisoned, and it is also helpful to maintain water quality.
In addition to water and fertilizer, too high feeding density can also lead to white bubbles on the water surface. If there are more fish, there will be more excrement, and the water will go bad easily. Therefore, it is necessary to reduce the feeding density. There is only one way to reduce the density of fish ponds, that is, to fish out some fish and put them in other places.
change is a water problem, regular water change can also solve the problem of white bubbles. Usually the cycle of changing water is uncertain, according to the deterioration of water quality, if the fish pond is relatively large, the water quality can be maintained, so there is no need to change too frequently. If the fish pond is smaller, it is necessary to change the water frequently, usually once every seven days.
water and fertilizer is often man-made, because too much food is fed, resulting in an increase in organic matter in the water, which will produce white bubbles after being decomposed. In order to avoid the recurrence of similar situations, we must control the amount of feeding, feeding fish to do a small number of times, so as not to pollute the water quality.
