The middle-aged customer finally made up his mind to buy a 1-meter-long aquarium, and the welder Zhao kept pouting beside him.

"What's the point of buying 1 meter? After a while, the grass will still grow in my heart!" said Zhao welder.

Middle-aged customer: "That...... Buy 1.2 meters?"

Zhao welder: "If you want to buy it, you can buy the longest one, even if you don't buy 1.8 meters, at least you have to buy 1.5 meters!"

The middle-aged customer waved his hand again and again: "No, no, it's too big......"

Zhao welder: "It's not big, it's not big, my cylinder is 1.5 meters, it's not big at all!"

Middle-aged customer: "It's really too big......"

1.2 meters is only 20% longer than 1 meter, but the price is much higher than 20%, because the area is more than 20% larger. As the water capacity increases, the corresponding filtration equipment should also be replaced with a higher power, otherwise the filtration effect will not meet the standard. All things considered, a 1.2 meter aquarium is 40% more expensive than a 1 meter one, and if it's larger, it's even more expensive.

Zhao welder is obviously generous to others, anyway, it is not him who pays for it, if he is dozens of years younger, it is estimated that he is also a member of the card bar plus money party...... But he has a loud voice, and whoever has a loud voice is justified.

After some prodding, the middle-aged man was really tempted by him, and it may also be for the sake of face, so he finally changed it to a 1.2 meter 2 aquarium, and it came with a full set of aquarium equipment.

This is the first aquarium Zhang Zi'an has sold, and it is still designed by himself, and he can get the recognition of customers, and his heart is full of a sense of achievement.

"But boss, why are your fish tanks so low? It would be nice to be taller, and you can hold more water and raise more fish in the same area. ”

When it came time to pay, the middle-aged customer asked regretfully.

None of the fish tanks in Zhang Zi'an's store, no matter how big or small, except for a few fish tanks that are not for sale for display, are more than 60 cm high.

Netizens answered this question for him - obviously because Zhang Zi'an slammed the door, the length and width could not cut corners, so they did things from the height.

Zhang Zi'an led him to an empty fish tank and motioned: "The height of this fish tank is 60 cm, you can put your hand in it and try it." ”

The middle-aged customer didn't know why, but he still reached into it according to his words, and was surprised to find that because his armpit was pressed against the wall of the tank, his palm could not touch the bottom of the tank, but his fingers could touch it.

"The average person's arm is not that long, and the reasonable design height of the fish tank is only 60 centimeters at most, otherwise it is too troublesome to maintain and clean up, because the hand cannot touch the bottom of the tank, unless you are 2.2 meters tall, or put the fish tank directly on the floor. Zhang Zi'an explained that letting the other party try it for himself is more convincing than words.

Including the soles, the middle-aged man's height is about 1.7 meters, which is not short among middle-aged people of a similar age, and the proportion of arm length is also within the normal range, but even so, his fingers can only barely touch the bottom of the cylinder, and if he wants to pick up something from the bottom of the cylinder, he has to stand on tiptoe.

Because large aquariums are equipped with base cabinets, and there are various filtration equipment in the bottom cabinets, it is obvious that the fish tanks cannot be directly placed on the ground, but all large fish tanks cannot be made too high, except for a very small number of display tanks or customized according to the actual needs of customers.

The middle-aged man's question was answered, and he was about to say that he understood, and then Zhang Zi'an further added: "In addition to the inconvenience of maintenance, there is another reason why the fish tank cannot be made too high - if the water is too deep, the light intensity placed on the top is not strong enough to penetrate the seawater, and the corals and other aquarium creatures at the bottom will not get enough light." ”

Electrician Wu listened attentively, while Welder Zhao said proudly: "Look, although the fish tank in my house is glued by myself, it is not too high, at most 70 cm, who makes me tall, does this mean that I have the understanding of raising fish?"

The others didn't pay attention to him, only Wu Electrician continued to complain: "If it was shorter, it is estimated that the Bobbit bug would have crawled out a long time ago, maybe it would have ...... into your bed in the middle of the night."

Electrician Wu suddenly remembered that this was a public occasion, and there was a young girl like Xiaoxue, so it was not suitable to make an oversized joke, so he swallowed the second half of his words back.

Zhao welder: "...... Old Wu, if you don't run, I'll die?"

Electrician Wu smiled and said no more.

Seeing them like this, Zhang Zi'an estimated that after Wang Qian and Li Kun got old, they would probably be like this.

They have been in the store for a long time, and if they don't come home, their wife may call and urge them to go back for lunch.

Wu electrician selected a few of his favorite fine fish, according to his meaning, persuaded Zhao welder to buy it here, don't go to another aquarium, save running around and maybe be pitted.

Zhao welder also picked a few fish, but he didn't pay immediately, but asked Zhang Zi'an to keep it for him first, the price is based on today's calculation, he wants to go to another aquarium to see, if the fish there are better and cheaper, don't want the fish here.

To be reasonable, this request is very unreasonable, so angry that Electrician Wu sighed again and again, and he didn't know what to do.

Zhang Zi'an felt that although Zhao welder was very fond of taking advantage, he was still a good person, his personality was really bold, and he had something to say, so he agreed: "Okay, today is the opening celebration of our store, everything is negotiable, I will agree to your request - but the words are ahead, not an example!"

"Don't worry! I'll leave it here, there will be no next time! When I go to that store, if the fish is not as good as yours here, I will buy it from you in the future!" Zhao welder heard this, felt that he had earned 100 million, and patted his chest and promised.

Electrician Wu is still counting him down, it's just too embarrassing, and he doesn't want to go out with him in the future.

Seeing that Zhang Zi'an was going to help the middle-aged customer answer some additional small questions, Zhao Welder quietly pulled Wu Electrician aside and said in a low voice: "Old Wu, you don't know, I heard that Wang Carpenter is going to turn over the tank in a few days, and he may eliminate a batch of old fish...... I thought to myself, maybe I could come over and buy a few less......"

"Overturning?" Wu Electrician has heard this word, which is to tear down the ecosystem in the fish tank and reopen the tank, and re-open the tank.

There are many reasons for the overturning of the tank, some are due to problems with the fish, some are devastating disasters in the ecosystem in the tank, and some are purely because the owner is idle and the eggs are painful, and there are various reasons.

"Yes, I'm going to visit it then, and I'll ask for a few fish. Zhao welder said with a smile.

"Is there a problem with the fish he raised before?" asked Electrician Wu.

"This ...... I don't know, whatever! Why don't you take advantage of it!" said Zhao welder nonchalantly.

Electrician Wu vaguely felt that something was wrong, but there was no reason to persuade him, so he had to go.
