Hangtai Aquarium: you can become a master without rigidly abiding by the formula.

Many articles on biofiltration are beneficial, but they are too professional. In fact, the reason is very simple, the so-called biofiltration is the concept of old water in Chinese fish farming. Old water is the most suitable water for fish farming.

So, it takes means to create this kind of old water; from a scientific point of view, the old water is caused by nitrifying bacteria in the water. How to produce and maintain nitrifying bacteria in water, that is, the process of establishing and maintaining biological systems, in Chinese fish culture, that is, the process of water drying, breaking into tanks, filtering, etc., from new water to old water, and how to keep the old water unchanged to clear water or even dead water.

Nitrifying bacteria need oxygen, the flow of water, etc., and it is the same reason to keep old water. Since the introduction of biochemical filtration, nitrifying bacteria, activated carbon, ammonia-absorbing stone. And other things related to biochemistry came into being. These methods must be useful and scientific. But is nitrifying bacteria really that complicated?

In fact, with a strong circulating filtration system, light and necessary intrusion into the tank, the water in the tank will naturally become old water, and there is no need to buy a lot of things for nitrifying bacteria. Chinese people have a longer history of fish farming than foreigners, and they can raise fish very well. Coupled with the adoption of some of the methods and equipment of foreigners, they can raise fish better. In other words, there is no need to be too superstitious about foreigners, the combination of native and foreign countries is better. And you don't have to spend so much money. Specifically, there are the following points:

I. can the circulation strength of the pump absorb garbage?

Observe the circulation of water in the tank to see if fish droppings can be inhaled by the pump. The water intake of the pump and the outlet of the filter tank are adjusted to the best position, so that the feces are sucked into the filter tank by the pump with the flow of water. In order to make the pump work better, buy a pump a little larger than the conventional one, that is to say, if you use a 30-watt pump with a 1.2-meter cylinder, you will buy a 36-watt one. Leaving no feces in the tank is the key. In addition, the color culture is afraid that the water will rush to the fish, so that the water outlet can be rushed to the cylinder wall, so that the water will hit the cylinder wall in the cylinder, and then flow back to the inlet of the pump.

Second, thicker filter cotton can be chosen as the bacterial bed.

This is enough, relatively thick cotton can be very good cultivation of bacteria, there is no need to spend money on bacteria, bacteria bed, and so on. In comparison, sponge is better, more economical and practical, filter cotton wash several times will be dilapidated, to change for a new one, and the sponge takes longer. Although each wash, the stolen goods will wash off part of the nitrifying bacteria, but will leave enough nitrifying bacteria to become seeds, the role of the pump, coupled with sponge both filter and nitrifying bacteria bed, coupled with the cylinder wall, cylinder decorations are good bacterial beds, old water is also produced. In addition, due to the thick filter cotton, it is possible to store water in the upper filter tank and overflow, so just raise the screen pad in the slot. Explanation: the sponge should be that kind of fine, the new permeability will be worse, just use a section of it.

Third, do not worry and cling to the formula

As for the pH value, softness and hardness, which can be handled flexibly according to the situation, fish farming is a kind of entertainment, which is as tiring as learning. Most of the fish we raise are not wild, and they have basically adapted to the pH of our water from generation to generation. After all, from buying fish in the south to raising fish in the north, it is also a minority. As long as the water is kept in an old state, the acidity and hardness of the water will not be a problem.

Fourth, regular water change should not be ignored.

Even if the water is not mixed, it is still necessary to change the water, one to three or one to four at a time, but with the above mentioned, there is no need to be so frequent. Many friends have a misunderstanding, ha, that is, they never change water, and when there is less water, it is more or less the same, because the purpose of changing water is to inject new water into the fish tank to decompose trace toxins in old water, and if you can add water regularly, you can also ignore the step of changing water.

The heart always knot.

In the past, Chinese people raised fish in pots and siphoned, and the old water was kept for a short time. Nowadays, with the pump, the old water in the tank is kept for a long time. In order to keep the water in the old state, the pump is very important. The pump circulates the water, and the filter cotton or sponge not only filters but also acts as a bacterial bed. A 1.2 meter cylinder, with an out-of-cylinder filter and two layers of sponge, there are no amine-absorbing stones, bacteria and the like, and the sponge completely plays this role.

The longer the sponge is used, the more precious the two sponges are. Because they not only block the dirt, but also act as a bacterial bed. This is how old water (that is, the biochemical cycle) is produced and maintained. If the fish culture in the new tank can equalize two pieces of cotton filter from the old tank, then the establishment of old water will get twice the result with twice the effort.

Chinese fish farming has a long history, but it suffers from less scientific summary and more folk experience, saying that there is no formula and no provisions, while foreign fish farming pays attention to science, such as ph, nitrifying bacteria, biochemistry, physics and so on. Fish farming does need this expertise, but if it is too professional, it becomes academic research. Maneuverability and fun will be much worse. People who have just learned to raise fish are intimidated or even deterred. I think it is better to combine Chinese traditional fish culture with scientific basis. More interesting and operable. The water is changing, the fish is also growing, the water and fish in the tank will also change with it, only some data is far from being replaced.
