Hangtai Aquarium: How to maintain the stability of aquarium water quality in the process of raising ornamental fish?

When raising ornamental fish for a long time, the good water quality of the fish tank will be damaged, which will lead to fish disease, turbid water and so on. Even if the timely remedy is carried out, it is also very troublesome, so how to maintain the balance of the fish tank water quality?

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.

The stability of water quality depends to a large extent on the stability of microecosystem. The stability of microecosystem is mainly shown in the following aspects:

1. Be able to adapt to the pressure of external changes in a short period of time, maintain one's own survival ability and maintain the integrity of the collective traits of the system.

2. It has the ability to resist and repair environmental pressure. When the environmental pressure does not exceed a certain range, the system can resist this pressure and remain stable. If the environmental pressure exceeds its resistant range, part of the function of the system will be lost due to the death or inactivation of some microbial groups. At this time, the rest of the system can form a complete ecosystem with the emerging groups, that is, repair.

3. Adaptive adjustments can be made according to the changes of the environment, such as the periodic adjustment following the seasonal changes.

Stability is related to the diversity of microorganisms, a stable system in which the species of microorganisms show a high degree of diversity and will not affect the overall structure because of changes in individual populations. When the species of microorganisms reach a certain degree and form a relatively balanced structure, the system can achieve high stability.

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.
