Can digestive bacteria be mixed into fish feed in koi fish?

Of course. First put nitrifying bacteria, culture water, and then put fish. If there is fish in the fish tank, it should be added near the water inlet. The suction tank will be attached with rings, biochemical cotton and bottom sand, which are places where nitrifying bacteria live. Pay attention to washing the bottom sand. Dosage of nitrifying bacteria (according to a 40-liter fish tank): Day 1: Put 25 ml nitrifying bacteria into a 40-liter fish tank! The next day: 10 ml nitrifying bacteria were put into a 40l fish tank! Day 3: 10 ml nitrifying bacteria are put into a 40l fish tank! The above control is to turn off the lights and turn on the itch machine. Matters needing attention in raising koi fish: 1. The change of water temperature koi fish is afraid of the rapidly changing temperature. When changing water, be careful not to give the fish "bath water" and inject it slowly against the cylinder wall. The temperature difference should not exceed 2 to 3 degrees Celsius in a short time. 2. If koi fish wants to maintain good water quality, it must have strong filtration ability if it can eat and pull. 3. Diversity of food koi fish is an omnivore, and it can be fed with minced vegetables, garlic and bread worms 1-2 times a month. 4. koi fish swims vigorously in the bare fish tank. There are too many decorations and stones in the cylinder, which may easily cause koi fish to scratch and cause pathological changes (such as perforation and imprint). 5. Use less medicine and provide more oxygen. Koi fish is aerobic, so it is best to use an air pump to supply oxygen for 24 hours. In case of illness, try to use less medicine and increase oxygen supply.
