Anonymous users2024-01-23Cooling is needed.
Generally speaking, the most suitable water temperature for tropical fish is between 20 and 30 degrees, but different tropical fish species have different requirements for temperature, such as guppies and swordtails can tolerate low temperatures of about 10 degrees; Arowana can survive at temperatures higher than 30 degrees, but should not exceed 35 degrees at most, because if the water temperature is too high, the fungi in the water will multiply in large quantities, and it will also affect the appetite of the fish. For the golden dragon or the red dragon, it will also affect its hair color, and even the increase of fish diseases. Therefore, when raising tropical fish, it is necessary to control the temperature of the water in order to make the tropical fish grow healthily.
This is the reason why the fish tank cools down in the summer.
Western restaurants don't need to be divided into cold days and summer bars, but the drinks need to be cold on cold days and hot drinks on hot days.
First of all, your restaurant is equipped with air conditioning, which should be an enclosed space, and secondly, the customer has a cold and asks to turn off the air conditioner, then you can only explain the situation to the other party to understand, after all, there is no absolute fairness in the world, you can only do your best to meet the needs of most people.
Whether it needs to be changed depends on whether the water quality can still maintain the demand for fish.
The refrigerator should be placed in a ventilated place, and the contents of the refrigerator should be separated from raw and cooked, and there should be space, and it should be deodorized regularly.
Nice Italian restaurant, small, with a foreign feel. The noodles and appetizers were delicious. My favorite is his vegetable soup. The attitude of the waiters is also very good, I really recommend it.
