It will take three to five days at the fastest to raise fish in the new cement pond. If it is slow, it will take about half a month.The reason why fish can not be raised immediately is that the new cement pond contains cement alkali, which can reduce dissolved oxygen and is harmful to the health of fish, so it needs to remove alkali before it can be used.There are many ways to remove alkali, which can be slowly removed by soaking in water or neutralized by other substances.
1, disinfection: After the new cement pond is built, the first thing to do is disinfection.Disinfection method is very simple, generally use potassium permanganate immersion, but if the cement pool is too large, with potassium permanganate on some waste, you can use bleaching powder or quicklime, the whole pool sprinkle static for a few days, and then drainage cleaning can be.
2. Alkali removal: If you want to remove the alkali in the cement tank, you can soak it in clean water and change it every 2-3 days. It usually takes 15-20 days to completely remove it.If you want to be quick, you can use vinegar or ice vinegar to neutralize it and soak it for 2 days.
3. Water test: After alkali removal, water needs to be raised again. Dry the water for a few days and then pour it into the cement pond. Then put it for a few days to get used to it. Test the water with some well-raised fish. If there is no problem, you can continue to raise it.
