Main points of breeding Koi in fish pond
For the newly built cement fish pond, the alkalinity on the wall of the pond shall be removed before use. In the way of alkali removal, fill the tank with 0.25% phosphoric acid solution, soak for one to two days, and then wash the wall of the tank with clear water. After the fish ponds are washed and cleaned, soak them in dark green water for about ten days, wait until the walls of the fish ponds are mossy, and then try to raise them again. Only when the safety of water source is determined can carp be placed in the pool. In addition, Koi should be raised in the pool when they grow to 10 to 20 cm.

Feeding management of Koi in rainy season
1. Before the rain, the weather is sultry and hot, the koi's mood fluctuates greatly, and they are not very interested in food, just eat a little. At this time, remember not to feed more. The fish are animals without stomach, and they don't feel full. If they are fed too much, their digestive system is not good, and their anus will turn red easily.
2. Due to the low air pressure, the dissolved oxygen in the water will also be reduced, and in serious cases, it may cause a lot of damage to the fish.
3. The rainwater is very acidic. If a large amount of rainwater is mixed into the fish pond, the water quality will be greatly acidified. The acidified water is fatal to the fish who do not like acidity. The acid in the rain will corrode the fish body and attack its gills, causing the carp to rot its gills, fins and tail, and even catch water mould and white spot disease.
