484 浏览家中鱼缸一年没有清理，玻璃材质的缸壁上都是发绿的污物，似乎是一种藻类。因为观赏鱼就是用来观赏的，这些藻类阻挡了视线让我无法透过鱼缸欣赏，终于一次周末抽时间把水全抽出来，用百洁布、钢丝球擦除了，结果不到一周，又开始满满发绿。
直到一次去宜兴丁蜀的莲花荡游玩，看到很多人在捡拾螺蛳，我无意捡拾带回做成菜，只是觉得螺蛳也许可以净化鱼缸，于是就带走四个螺蛳放在了家中鱼缸了。
结果巧了，第二天发现鱼缸尽然变得通透，绿藻不见了踪影，一两只螺蛳还在缸壁上爬行。仔细观察，发现它们的嘴一直在吸缸壁上的藻类。
从此以后，不但缸壁一直透明干净，连缸底的石子缝隙中的污浊物也被清理得很干净。
我想，之前清理的方法就是西医治病的方法，直接且粗暴。之后采用的方法，正式道医采用的方法，自然且简单。而如果是普通中医的做法，大概是投入一些吃藻类的鱼，这样虽然可以解决藻类问题，但会带来其他生态问题。中医之中只有道医能解决疾病真正的根源，往往单用一种药或某个穴位就能解决病者痛苦，原因就在于此。
My fish tank has not been cleaned for a year. The glass wall of the tank is full of green dirt, which seems to be a kind of algae. Because ornamental fish is for viewing, these algae blocked my view and made me unable to enjoy it through the fish tank. Finally, I took time to draw out all the water at the weekend and wiped it with a cleaning cloth and steel wire ball. As a result, it began to turn green again in less than a week.
Until I went to Lotus Lake in Dingshu Town, Yixing City, and I saw many people picking up river snails. I didn't intend to pick them up and bring them back to make dishes. I just thought that snails might be able to purify the fish tank, so I took four snails and put them in the fish tank at home.
As a result, it happened that the fish tank became completely transparent the next day, the green algae disappeared, and some snails were still crawling on the tank wall. By careful observation, I found that their mouths had been sucking algae on the tank wall.
Since then, not only the cylinder wall has been transparent and clean, but also the dirt in the stone gap at the bottom of the tank has been cleaned up.
I think the previous method of cleaning up is the method of Western medicine, which is direct and rough. The method adopted later is natural and simple. If it is the practice of ordinary Chinese medicine, it is probably to invest some fish that eat algae. Although this can solve the problem of algae, it will bring other ecological problems. In traditional Chinese medicine(TCM), only Taoist medicine can solve the real root cause of the disease, and often a single medicine or a certain acupoint can solve the patient's pain,that is why I tell you this story.
