Who is responsible for putting on a new filter material and the fish is dead?

A fish friend responded that "the filter material was originally used to purify the water quality, but when the filter material was put on the fish tank, the fish died. There must be something wrong with the filter material. It was suspected that the heavy metal exceeded the standard, causing adverse reactions, but the seller refused to deal with it for various reasons. It's too irritating."

According to this fish friend, through the introduction of a friend, he began to raise rainbow fish for daily viewing two years ago. "this is a round fish, a tropical fish, an imported species, and it is relatively expensive. At the beginning, I bought all the small fish, which were more than 10 centimeters long. After two years of breeding, the big ones have grown to 35 or 6 centimeters long."

This kind of fish originally lived in the wild, with strong sensitivity and high requirements for water quality, so in the process of feeding, it is necessary to put some aquatic plant filter materials to purify the water quality. The aquatic plant filter material is a kind of granular bacterial ball, which is mainly used to cultivate bacteria, decompose and remove harmful substances and ensure the water quality of the fish tank. I have used this kind of filter material many times before, and I bought it in this store, and there has never been any problem. Five days ago, after the previous purchase was used up, I bought another batch. " Mr. Chen said.

"in the past, the price of filter material was 9 yuan per jin, but this time it was 5 yuan per jin. At first, I still had some questions. The salesperson said that there was a discount for old customers." The fish friend said that at about 2 pm that day, when he went home, he put in the configured filter material after changing the water as usual, ready to purify the water. "as soon as I put it in for a while, I found that something was wrong, and the two smaller rainbow fish immediately reacted; they were swimming in the water, suddenly lying at the bottom of the tank, unwilling to move, turned on the lower circulation pump, and the fish floated directly on the surface of the water, which was not normal."

After discovering the situation, the fish friend then called the seller to explain the situation. "after listening to the situation, the other party said that the problem was not big, and the PH value fluctuated a little, so you can increase the amount of oxygen pumped. Two slightly smaller rainbow fish died on the spot. Although the merchant said so, I was still a little worried and put the other one in another fish tank. " The fish friend said that because he had something to do that afternoon, he went out later, and when he came back, he suddenly found that four of the six big rainbow fish had died. "it was not easy to raise five of the eight fish. According to the current market situation, the loss was more than 5000 yuan. It's so heartbreaking. The emergence of this situation must be caused by problems with the filter media, but it is too exasperating to communicate with sellers for many times and refuse to deal with them for various reasons. "

And this fish friend found a newspaper reporter, hoping to expose this unscrupulous businessman.

Seller: it is caused by the farmers themselves, not our responsibility

The reporter contacted Manager Xu, the seller of the filter material. "when I received a response from a customer that night, I went over. There were many kinds of situations that caused the death of Hongyu. It was judged that this was caused by the farmer's lack of experience in fish farming, and it was not our responsibility." In this regard, Manager Xu said.

Manager Xu told reporters that rainbow fish from Brazil, is a tropical fish, the species is more valuable, the market value is relatively high, so breeding is also particularly strict. "raising fish and water first is a necessary knowledge for tropical fish, and the most important thing for rainbow fish is water quality, and even a small change will cause them to overreact. Conditions such as hypoxia, deterioration of water quality and sudden changes in water quality can be the causes of their death reactions. " Manager Xu said that as many indicators of domestic water consumption are not up to standard, it is necessary to use these filter materials to cultivate digestive bacteria and stabilize water quality.

"the situation of the farmer belongs to improper operation, resulting in ammonia poisoning of rainbow fish." Manager Xu said that the customer's fish tank belongs to the old tank. Because the fish eat, drink and scatter in it, there is more feces, and there is more ammonia nitrogen in the tank. If the filter material is not changed, the ammonia nitrogen will definitely exceed the standard. "according to the requirements, before changing the filter material, the fish tank should be washed several times, but because the filtered water was not drained clean during the change of water, there was a reaction. As soon as I received a report that night, I went over and dissected the dead fish and found that there was something wrong with the intestines of these fish. It would be better if they were not replaced. As soon as the filter material was changed, the PH value in the water rose rapidly, causing the fish to die. "

Manager Xu said that in order to test the quality of the filter material, after discovering the situation, he did another experiment and put the rest of the customer's filter material in his partner's fish tank and found that there was nothing wrong with the fish. "later, we were worried, so we did another test and put the filter material in water for two to three hours. After the bacteria were completely released, we carried out the test and found that the PH value and other aspects were up to the standard, and there was no problem. The filter materials we sell are all from regular manufacturers, and there is absolutely no problem with the quality. in this case, if customers feel that there is a problem, they can find a special organization for testing. If it is our problem, we will certainly bear it. " Manager Xu said.

City Consumer Association: need to divide the responsibility after the identification of the filter material

How to deal with this matter, the reporter consulted the Municipal Consumer Association, its staff said that if the two sides do not agree, this situation needs to be identified, there is no test certificate, it is impossible to say that there is a quality problem. "in this case, it is recommended to go to a testing institution recognized by legal institutions for testing. If it really cannot be detected, you can ask fishery experts to conduct on-site investigation, and ask the fishery department to show proof, which can also achieve certain results. If it is found that there is a problem with the filter material, the seller and the manufacturer shall bear the responsibility; if it is caused by other reasons, the seller and the manufacturer will not be directly responsible; if the mediation between the two parties fails, it can be resolved through legal procedures. " The staff member said.

The editor thinks that the public argument is reasonable and the mother-in-law is reasonable. What do you think of this matter?
