What should I do if the bottom sand of the fish tank is stinky?

During the communication with the fish friends recently, I found that you are more concerned about the problem, that is, after the bottom sand of the fish tank is spread, some fish feces can not be cleaned up, which leads to the problem of the smell of the bottom sofa of the fish tank. In this article, we will discuss the topic with you.
First of all, let's take a look at why the fish tank should be covered with sand. After keeping fish for so long, in fact, the bottom sand of the fish tank is nothing more than these reasons. On the one hand, it is to beautify the fish tank, that is, the bare tank is not so ornamental after all. Therefore, laying some bottom sand on the fish tank can play a certain decorative role. The other one is the water tank or the fish tank landscaping, which definitely needs to be sanded. Because the bottom sand can root the aquatic plants, and also allow some stones or wood to have some fixed attachment points, therefore, the fish tank landscape or the aquatic tank must be the bottom sand.
Why does the bottom sand of the fish tank smell? The main reason is that if the bottom sand is made of some materials with relatively weak permeability, it is easy to spread it thickly after a period of time, due to the precipitation of food debris or fish dung, and then slowly lead to some Heterophilic bacteria grow, and the bottom sand begins to smell.
However, everyone should note that this is only the case with some air-tight materials. If some air-permeability is better, there will not be this problem under the fish tank. So which materials have better air permeability and which ones are more general?
If it is to grow flowers and grass, there are actually many materials with better air permeability, but at present, our aquarium fish tank has better air permeability as the bottom sand. Only ceramsite is the one. I hope there will be more in the future. Other bottom sands are generally more breathable, like our common fine sand, or iron sand, or some colored stones. In fact, their breathability is very general. When these are thick in the fish tank, It will easily cause the bottom sand of the fish tank to smelly after being used for a period of time.
However, if you prefer fish tanks, friends of landscaping should know that these bottom sands are actually indispensable. We still need to use some, but in the process of use, it is recommended not to lay so thick, about 1 under a fish tank 2 cm will not have such a problem.
Is everyone still thinking, is it lack of water and grass mud? In fact, the water grass mud is between the two. Depending on the workmanship, some water grass mud is still breathable, but some water grass mud is not very breathable if the workmanship is more general. In any case, the water grass mud contains certain nutrients, so its breathability is poor, and the water grass mud is not used to make the bottom sand of the fish tank very odorous, unless the water quality deteriorates particularly badly. Of course, if the water quality is particularly bad, ceramsite will do.
If the sole sand is for the fish tank, for the sake of better viewing, water grass mud is actually the first choice. The second is ceramsite. After all, the water grass mud has some nutrients and some trace elements, and it can also help regulate the water quality. The ceramsite is completely free of nutrients, and it has better permeability. However, the ability of ceramsite to cultivate nitrifying bacteria is very strong, which is not comparable to water grass mud. In addition, the two are black and red, so they also have a certain degree of appreciation for the bottom of the fish tank. Behind them are some ordinary fine sand or tropical rainforest sand. In fact, they are also relatively ornamental, but they cannot be too thick. But it also depends on the style of our fish tank. For example, if it is a South American-style fish tank, it is better to spread these tropical rainforest sands or fine sands. However, if you raise other ordinary ornamental fish, it is recommended to use grass mud or ceramsite. can.
Regarding the thickness of the bottom sand of the fish tank, it is recommended that you only 2-3 cm thick, unless it is aquatic landscaping, then there are some strong grass roots, you need to raise the water grass mud pad a bit, the comparison Thick, otherwise it is generally 2-3 cm to ensure that the thickness under this is moderate, and it will not smell easily.
