What should be used to disinfect the newly made cement fish pond? Edible salt, vinegar?

Sea salt, or potassium permanganate (note that this medicine is very toxic, and the dosage should not be excessive. Boil in a bowl and other containers before adding).

1. The pool should be filled with water first and soaked for more than three times, about 1 month.

2. after soaking, put a small amount of fish in the pond, and after one month, the fish can be officially released without problems. EM bacteria can be added when fish are released conditionally.

3. Water pipes will be exposed, which will affect the appearance. And is there enough filter material? Do you want to add more? Is the filtered environment conducive to the growth of nitrifying bacteria?

4. 1 liter of water 1 cm fish, novices can't pass this level.

Attention should be paid to fish farming: the water quality should be no problem, the temperature and light should be appropriate, the food should be of good quality and quantity, the operation should be gentle and slow, the drugs should be used with caution, and the toxic substances should be kept away (pay attention to the lampblack, insecticide and mosquito-repellent incense at home).

1. Don't use 1 liter water (length, width and height, 10× 10 cm) multi-cylinder and small filter to raise fish. If fish are raised with 1 cm, it is easy to get sick and die. When the water tank is at least 30 cm above, it is easy to maintain the water quality. Or if there is no filtering equipment, please calculate the fish according to the water surface area. Tropical fish need 30 square centimeters of water per centimeter (excluding caudal fin), and goldfish need 60 square centimeters.

open

The water in the cylinder should be disinfected with strong brine, washed with clear water, and then filled with water to enter the stage of water extraction. The water temperature in the cylinder should be between 28 and 30 degrees (the temperature of cold water fish should not be lower than 15 degrees), and the water should be raised.

Seven days later,

Or on the first day of hydroponics, "open the tank for three bacteria" or "open the tank for many bacteria (EM bacteria)", but pay attention to moderate weight, avoid light and ventilation, and release the fish in the tank after three days (

Soak the peeled raw shrimps in the water in the filter box until the shrimps are completely melted. If the whole cylinder opening period is filtered, it will not stop, and it will not be officially released until 20 days later, preferably more than 30 days.

Fish. Besides, you can't let the sun shine directly on the fish tank!

A () < 2 > in this paper; & lt3>& lt4> This means that there should be filtering equipment.

Fish or people who can use nitrifying bacteria can choose one of the four methods. B In addition, after the tank is opened, the normal temperature of fish should be determined according to the types of fish and aquatic plants, the needs of survival and treatment. After opening the fish tank, the fish is cleaned.

Cylinders should be illuminated, but not in direct sunlight. In addition, places where nitrifying bacteria live, such as filter tanks, must be protected from light and ventilated (if it is an inner filter or an outer filter barrel, it cannot be stopped. If the power is cut off for 2-3 hours, it is reported that nitrifying bacteria will start to die, no.

In the case of soaking water, the upfiltration is 8 hours, and the trickling filtration is 12 hours. ) c Fill up the water, not that you want to fill it up to the tank mouth, but to the right position, usually at a certain distance from the tank mouth, depending on the size and setting of the tank.

It depends on the specific situation.

3. When putting the fish, pay attention to put the fish and the bag into the tank together. /kloc-After 0/5 to 30 minutes, remove the water and bag and put the naked fish in the tank. During the period, water was added to the tank several times to make the fish adapt to not feeding the day before (be careful not to let the fish have white spots, white hairs, rotten fins and scales).

4.

Changing water depends on your water quality. If there is filtration, the number of tanks is large or small, but there is no filtration, and the number of tanks is small or large, so the water should be dried. When changing water, clean the filter cotton at the top of the filter tank with clear water (do not use detergent).
