Pet King

From the phrase "ceiling fish tank pomegranate tree, Mr. fat dog and fat girl", you can hear how old Beijingers like to raise fish and dogs. The rich and leisurely life of a quadrangle courtyard raises dogs and girls to fat.

In the late summer and early autumn, mosquitoes became scarce, and Mr. Jiaoshu's frustrated reading came from the study.

Take out a lounge chair and sit under a canopy full of purple grapes, peel off a red pomegranate, ripe pomegranate seeds burst out a sweet juice between the lips and teeth.

The fat old dog lay lazily beside the lounger, licking his tongue from time to time.

Due to the abundance of water vapor, the outer wall of the aquarium condenses fine water droplets, which slowly gather under the effect of gravity, and then flow down along the tank wall, soaking a piece of bluestone.

A pair of goldfish with bubbling eyes spit out bubbles, playing among the thick green lotus leaves.

The white and fat man head happily ran in the courtyard.

From this moment, the good life is closely linked with pets.

Nerdy cats.

Lively outgoing people keep dogs.

People who want to cultivate their sentiments and culture can raise fish.

Of course, the life of the Beijing Courtyard is not something that ordinary people can enjoy.

The old fish farming was basically extensive breeding, not too much, and cold water fish such as goldfish, grass goldfish and koi are very hardy, even in winter, you don't need to move the fish tank into the house. .

Besides, the fish tank in the Old Beijing Courtyard is not only used for fish farming, but also plays a fire fighting role. Once a room catches fire, the dog in the fish tank will extinguish the fire nearby.

Now the greenhouse effect is serious, and it can't get smooth all winter, but Beijing was quite cold in the past winter. After the winter, the water surface of the fish tank became thick with ice.

When the ice surface melts in the spring, you will be surprised to see that the goldfish in the fish tank swims back and forth, as if not affected by the freezing of the fish tank at all.

With the development of the times and technology, extensive fish farming can no longer meet people's needs, because people want to raise fish other than goldfish, grass gold, and koi, and raise some more delicate, more delicate, rare, and colorful It ’s time for all kinds of aquarium equipment to come out.

Some people who are more serious about fish farming will go to the fish market or buy some simple equipment online, such as heating rods, pumps, filters, and filter materials, and then buy some pellet feed to live together. The total amount is only 50 or 60 yuan. Money so that you can basically cope with at least half of the freshwater fish.

Someone who is more serious and knows how to check information on the Internet will add some nitrifying bacteria, take fish medicine, oxygen pump, and change the water tank regularly, so that they can feed at least 80% of the freshwater fish.

But marine life is much more complicated than this, Wang Qian and Li Kun stared at the dazzling array of equipment.

It is impossible to take care of the entire aquarium by Zhang Zi'an alone. Usually, Wang Qian and Li Kun must be in charge of daily affairs. Therefore, he pointed at these equipments and explained their uses one by one.

"We know this thing, is it a filter?" They said, playing with one of the devices.

"Well, but do you know what the filter is?" Zhang Zi'an asked instead.

They looked embarrassed. "Isn't this filter just a filter? Put some abrasive wheel filter cotton or something in it to filter out fish dung."

Zhang Zi'an chuckled: "The filter is not that simple. The most important thing in the fish culture equipment is the filtration system. The quality of the filtration system determines whether the fish in the fish tank can survive for a long time."

Filters are roughly divided into three categories, physical filtration, biological filtration, and auxiliary filtration.

Physical filtration is the filtering of fish dung and food residues that Wang Qian and Li Kun said.

Auxiliary filtration, the nitrogen cycle system, converts ammonia produced by the decomposition of fish manure into nitrate, which is almost non-toxic to fish.

Auxiliary filtration, including protein separator, ozone generator, calcium reactor, denitrifier and ultraviolet germicidal lamp, etc.

When he talked about one, he pointed them to the corresponding equipment and let them remember the shape and name of the soldier, so as to avoid confusion. As for the purpose of each equipment, it is not too late to remember it.

In addition, there are different kinds of lights, heating rods, hydrometers, various test strips and miscellaneous things.

Not all of these devices were mailed by Karl from Germany. Many of them were purchased online before returning to China. Some of the irrelevant equipment did not need to be too high-end.

Wang Gan took a hand net from a packing box and asked, wondering, "Master, it ’s not enough to buy a hand net. Why do you buy a box as soon as you buy it? It takes so many hands Copying the net? Is it that the seller refuses to sell only one, and only sells in boxes? "

Li Kun also feels the same. They all think that such extravagance and waste do not conform to Zhang Zi'an's usual style.

The specification of this whole box of hand-made nets is 100, divided into several colors.

"That's not it." Zhang Zi'an dragged, "I'm reminding you that if you need to fish out of the fish tank in the future, you must remember that each fish tank corresponds to a hand net, and must not be mixed, otherwise Once a fish in an aquarium becomes ill, it will soon infect all the fish. "

"Oh, it's like a syringe can't be used repeatedly?" Li Kun stunned.

"Almost," Zhang Zi'an affirmed.

When I usually go to the fish market, fish store or aquarium to buy ornamental fish, the customers see a thriving scene in the fish tank. When I see the owner smile and count the money, I never think that many owners open the store every morning. The first thing was crying and throwing dead fish out, so-called saw thieves eat meat, but no thieves were beaten.

Fish attacks are slow, have a long period, and are highly contagious. Basically, when the hair neck is gone, it is critical to prevent and isolate the source of infection in time. It is important but often overlooked to mix the net by hand. In the vector, many shopkeepers who open a fish shop with a hot head are paying tens of thousands or tens of thousands of tuition fees before they are enthusiastic.

In this regard, Carl specifically reminded him.

The first task that Zhang Zi'an assigned to Wang Qian and Li Kun today is to use sticker paper to affix a serial number to each handwriting net, from 1 to 100, to correspond to each aquarium one by one, and must not be mixed. ~ www.wuxiaspot.com ~ They nodded in agreement.

"Is there anything else I don't understand what it's for?" Zhang Zi'an asked again.

Wang Qian and Li Kun looked at each other.

Zhang Zi'an felt that their looks were a little weird. "What's wrong? Just ask if you don't understand. Don't pretend to understand." It doesn't matter. Who doesn't understand at first. "

"Master, we understand the truth," they murmured, "but"

"But what? If you have any questions, just speak directly." Zhang Zi'an urged, "I'll be fine for a while."

Li Kun took out a box from behind, "Master, you asked us to arrange the courier and move it over, but we really did n’t know what it was used for. We thought it was sent wrong at first, but the recipient was indeed yours. first name"

He tremblingly took out a set of pale blue bikini swimsuits from the box, carrying one piece in his hand.

"Master, can you tell us what are you doing to buy this?"

Zhang Zi'an looked light and light, "Oh, I bought it as a gift."

They said tearfully: "Don't lie to us, Master counts you as a ladies' lady, and we won't dislike you!"

"Where did the thinkers go? I am really giving away!" Zhang Zi'an clarified almost hopelessly.

God knows how the brains of these two second goods grow!

"But you have no girlfriend and no wife. Who do you want to buy a bikini for? A female friend is not the right place to send this?" They persisted in renting a question.

Zhang Zi'an was so embarrassed that he couldn't say that there was a mermaid in the bathtub, was it for her?

"Who the **** do I send you! I can't use it for collection?"

"Favorite?"

Wang Qian and Li Kun listened, looking at his eyes have upgraded from "perverted" to "great pervert"
