What do you mean by opening the tank? Does the new cylinder need to be opened?

What is meant by opening the tank, how to cook and start raising fish when the new tank comes back? Don't worry, today let's talk about how to open the new tank to hold water.

First, open the cylinder

Opening the tank is an important stage of water conservation, and whether the foundation is laid well or not will have a great impact on the future. Tap water is put into the new aquarium. After aeration to remove chlorine and increase oxygen, the fish can be put into the tank.

1. Configure a strong filtration system, including sufficient filter media

We generally divide the filter media into three categories: physical filter media, chemical filter media and biological filter media. In fact, most of the physical and chemical filter media also have biological culture functions. The purpose of configuring biofilter is to provide sufficient adhesion surface for all kinds of fungi. In the aquarium, if the growth and reproduction of fungi is limited by living space, it is difficult to adapt to the load of high-density feeding. If filter materials are used to expand the living space of fungi, stronger self-purification ability can be obtained than under natural conditions.

Adequate supply of oxygen

The decomposition of organic matter needs a lot of oxygen, which will reduce the oxygen content of water, which not only threatens the survival of fish, but also is not conducive to the growth and work of aerobic bacteria. Timely replenishment of oxygen loss in water is of great significance in the case of high concentration of organic matter. Nitrifying bacteria are typical aerobic bacteria, which can form effective ammonia oxide and nitrite during hypoxia, and when ammonia and nitrite reach a certain concentration, they will also cause the death of fish.

3. Introduce beneficial bacteria and choose nitrifying bacteria or compound bacteria (including nitrifying bacteria).

Nitrifying bacteria are everywhere, and as long as there are suitable conditions, they will multiply. However, nitrifying bacteria belong to autotrophic bacteria, which must synthesize organic matter in the body and reproduce slowly. if enough nitrifying bacteria are put into the aquarium, the establishment of nitrification system can be accelerated. Under normal circumstances, after about a month or so, the nitrification system can be initially established, and the concentration of organic matter in the water is also reduced to a relatively low level. At this time, fish culture can be formally established.

II. System stability

After opening the cylinder, it is generally best to gradually increase the amount of feeding, because at this time the biological system is not stable, the ability to resist impact is relatively poor, it is easy to cause problems if it is not handled well. The more common problem is that the capacity of the filtration system is insufficient, or the feeding density and feeding amount are too large, the discharge of organic matter exceeds the self-purification capacity of the system, and the water body begins to eutrophication. The solution, one is to strengthen biofiltration (can also be combined with physical adsorption and other auxiliary means), the other is to reduce the feeding density and feeding amount, in addition, through the exchange of water dilution, which is the most simple and effective method, but over-reliance on water exchange to maintain water quality will reduce the stability of the system.

It is difficult to say how long it will take for the system to be stable after opening the cylinder, maybe a month, maybe a few months, and some aquariums are even in an unstable state for a long time. The factors that affect the stability of the system are very complex, the more common are the weak biofiltration system and insufficient load capacity, in addition, casually increasing the number of fish or changing species frequently, feeding irregularly and irrationally, not changing water in time, excessive cleaning of filter materials, opening and stopping when the filter is on and off, and improper practices such as casually using drugs in the cylinder will hinder the stability of the system and even cause the system to collapse.

III. Daily maintenance

Even the best water needs to be maintained. in this sense, water culture runs through the whole process of fish culture.

The daily maintenance of aquarium is a big problem, including fish breeding and management, water quality monitoring, equipment maintenance and so on. The mixed culture of different fish species, the selection and feeding amount of feed, the prevention and quarantine of fish diseases, the requirements of water temperature, PH value and hardness of special fish species, and the reproduction of fish all belong to the category of fish breeding and management, some of which are related to water culture. Filters, filter materials, pumps, oxygen pumps and other equipment are also important factors affecting water quality.

For a good aquarium ecosystem, the daily maintenance of water quality is relatively simple, as long as the feeding density and feeding amount of fish are controlled, the normal operation of the filtration system is ensured, and the water is changed at the right time. Of course, the water temperature and PH value should also be observed and adjusted if necessary.
