Today we continue to talk about the topic of fish tank water purification, yesterday with you to share the bottom sand water purification, I found that everyone is still very interested in this topic. Today we are going to talk about a biodegradator's method of water purification, but also by a fan in the comment area of the article reminded, I feel that it is necessary to share with you.
Field snails should be familiar to everyone, as well as stone snails (there are more in Guangdong), these common freshwater snails are regular customers in our vegetable market. But people always covet their delicacy, and their water purification function is rarely mentioned. Friends who have raised field snails should know that if you raise field snails in a small fish tank, you will find that there are many viscous things that are visible to the naked eye, which are secreted by field snails. Speaking of which, do you think that these secretions are the key to treating water quality? In fact, it is not, these are the excrement of the field snail, they are a disadvantage of the field snail, I just say it first, so that everyone has a psychological preparation, the so-called "want to promote the first inhibition" well.

In fact, the field snail is in the biological chain belongs to the role of the "decomposer", they will deal with the decomposition of the organic matter in the water body, or dispose of some algae spores, as well as some simple algae. This is similar to the principle we mentioned earlier about using tool snails such as onion snails and zebra snails to treat algae.
However, different snails have different habits, so they play a different cleaning effect in the fish tank. For example, abalone snails, onion snails, zebra snails, etc., which like to climb on the walls of the tank and stone wood, are good at handling the algae hanging on them, and have been nibbling on the algae. The snails, stone snails, Malay snails and other snails that like to drill bottom sand are good at ingesting plankton and organic matter in the water body through filtration for a living.

You can take a look at the water purification effect of the field snail under the comparison of this picture, because I have been doing this experiment for a long time, and now there is no field snail to give me time to take pictures, so I found some other netizens on the Internet to do the experiment comparison chart for everyone to see. It took almost an evening before and after, which was enough to see the water purification effect of the snail.
From the picture, we can also see that the field snail is miraculously effective against this viscous and turbid water quality, and the most common viscous turbid water quality is green water. Green water due to sufficient sunlight, coupled with the usual feeding we feed a lot, resulting in too much organic matter in the water, excess nutrition, that is, we often say "eutrophication of water", which leads to the crazy breeding of green algae. The green algae float in large quantities in the water body, forming a green water that is visible to our naked eyes. But this is exactly the delicacy in the mouth of the snail, so throwing the snail into the green water is equivalent to letting them eat a big meal in the cafeteria.
Of course, after this big meal, there will be what we said earlier, the snail will secrete some viscous things, but these things are not easy to dissolve in water, so directly fished away or pumped away with a hose, if it is a larger fish tank, you can even use the tube, wait for the filter to slowly suck away.

Food is naturally not to worry, because while purifying the water quality, the snails are constantly eating, so don't worry about them being hungry, unless your water quality is too clean. Then the most important thing, my personal breeding experience, is still the bottom sand, soft bottom bed is the favorite of the field snail. Because the bottom bed will grow a lot of microorganisms, these are the delicacies of the field snail. Those snails that were raised with an empty shell that were soon left were basically the cases that occurred in the bare tanks with little bottom sand.
Although the snail will burrow into the bottom sand, friends who may raise aquatic weeds will worry that the aquatic weeds will be affected. In fact, it is not necessary, because once your aquatic weeds are fixed, their roots are very firmly rooted, and they will not arch the aquatic weeds because of the drilling of the field snails. On the other hand, if it is a water weed that can be easily arched by the field snail, it also proves that it is not well raised and the roots are not firmly rooted. And the field snail drill bottom sand can also play the role of "loose soil", play gardening friends know the importance of plant loose soil, to let there be a certain gap in the soil, there is a certain amount of oxygen, not to let the roots lack of oxygen. The same is true for the bottom sand of the fish tank, and the thicker the bottom sand, the more it is necessary to loosen the soil from time to time. This also answers the questions of some netizens by the way, the bottom sand will become a source of pollution will become corrupt reasons, that is, too long to loosen the soil, the oxygen content is insufficient, breeding a large number of anaerobic bacteria caused.
Finally, speaking of this, I feel sorry for eating field snails all the time, after all, its role is so great. In fact, there is a reason for mentioning the snail to everyone is also because it is our native snail in China, on the one hand, it is easy to obtain, on the other hand, I hope that everyone can pay attention to this not very remarkable creature. I didn't expect that the small snail in the wet market had such a great water purification effect!
If you also like to raise ornamental fish, you may wish to pay attention to it, all you want for fish farming is here.
