How to change water and wash cotton in San Fu Tian to avoid water quality turbulence？

　　Recently, the country has entered the three-day days and turned on the steamer mode. On a hot summer day, some fishermen have caused water quality turbulence and turbidity due to careless operation when changing water. Today we will take a look at what problems need to be paid attention to in the daily maintenance of the fish tank in the summer season.
1. Change the water without washing the cotton, and wash the cotton without changing the water. In other seasons, washing the cotton and changing the water at the same time will not cause any problems, but in the three days, if you do both things at the same time, you are in the tank.At the beginning or when the stocking density is too high, the problem will be quite serious.
You may wish to follow this principle, that is, change the water without washing the cotton, and wash the cotton without changing the water.This will greatly avoid the problem of fish tank water quality under the double pressure of changing water and washing cotton.In fact, we can stagger the two time points, for example, after changing the water in the fish tank, and observe for a period of time, when the water quality of the fish tank does not have any white turbidity, we then clean the filter cotton.
2. Dont over-wash the cotton. Over-washing the cotton is a problem that we need to pay attention to at any time. We must not underestimate the dirty filter cotton in the fish tank. This thing plays a crucial role in the quality of the entire fish tank.The important role is that once the cleaning is over, the entire water quality collapses instantly, which is not welcome at all.Simple rubbing, rinsing lightly, it is possible to use the original water or tap water.
3. The cleaning strength of the filter cotton under different circumstances 1. No biochemical filtration, only one or two filter cotton. For this equipment, the entire filter cotton is the heart of the water quality of the fish tank. If there is only one filter cotton, we might as well divide it into oneSecond, cut it with scissors, half and half of the cleaning, do not clean too clean.
2. There are biochemical cotton and multi-layer white cotton. If there are biochemical cotton and multi-layer filter cotton, then we only need to clean the top layer of white cotton. Other filter cotton must not be considered.
3. Have a strong biochemical filter as the foundation. If our fish tank has a strong biochemical filtration system as the foundation, the cleaning time of the filter cotton can be properly extended.We should also pay attention to this point, not to say that in this season, the filter cotton is a little dirty and we have to clean it.Even in the three days, if the feeding density of the fish is not high, we have a strong biochemical filter material as a foundation. It does not matter if the filter cotton is washed or not, as long as they do not overflow or cannot be seen.
4. Should we change the water when the air pressure is low or rainy?We also have to look at this issue from both positive and negative aspects. The so-called low air pressure and do not change the water on rainy days. The main reason is that the water quality will cause shocks in the water change.Water is incorrect.But if our water quality has deteriorated, the ornamental fish will continue to pant due to lack of oxygen, and it is certainly not appropriate to not change the water.If we encounter the above extreme situation, we can change the water completely, keep the oxygen supply, change a small amount, and pay attention to the above problems, then there is no problem.
