How to raise a courtyard fish pond?

Don't put sand and mud, bare pool is the best, mud is difficult to clean, water is turbid, sand is easy to pile up garbage and not easy to filter.

There is also that flowers and plants should not be planted directly in the pool. It will be more beautiful to plant them around the pool.

All cement ponds should be soaked in water. Generally, the water should be drained after one month, washed again, drained and filtered 1 week before the fish can be released. Tiles can be soaked for a week.

Koi fish is the most ornamental pond keeper. I suggest you raise koi fish.

1.3 square is more than 60, considering that koi fish can reach more than 50 centimeters in adulthood.

2. Goldfish, if it is grass goldfish, can't be written in one language or the following words.

3. Once or twice a day, around 9: 00 and 17: 00 during the day.

4. For breeding, the depth should be greater than 1 m, and for ornamental purposes, not more than 40 cm.

You have so many fish that you may not be short of oxygen for the time being, but it is very important in the future. Pay attention to your cylinder filtration.

6. Changing water depends on the garbage generated by your fish, usually once every 7 days to half a month, but your pool may be shorter, especially in summer, and it may be changed every day, which is not good for fish.

7. Yes, but your fish eat grass unless you have other ponds, vats and so on to purify water. In the case of barrels, water circulation, plant light and beauty should also be considered.

There are so many fish in your pond, I suggest installing a filter.

note:

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.

The following are the main points of fish farming in family fish tanks. You can learn from the following:

Pay attention to fish farming: the water quality should be no problem, and the temperature and light should be suitable (there should be light, but the sun should not be directed at the fish tank! ), food quality and quantity, gentle operation, careful medication, away from toxic substances (usually pay attention to the lampblack, pesticides 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.

2. After opening the can, the water should be disinfected with strong brine, washed with clean water without residue, 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 (cold water fish, the temperature should not be lower than 15 degrees). After 7 days in water, put a few fish with strong vitality into the tank for 30 days (or add nitrifying bacteria every day after 3 days in the tank). Avoid light) (or open the tank with "three bacteria" or "multi-bacteria (EM bacteria)" on the first day of hydroponics, but pay attention to moderate weight, avoid light and ventilation, and put the fish into the tank after three days) (or soak a peeled raw shrimp in the water of the filter pool on the first day of hydroponics until the shrimp is completely melted). You can't stop filtering during the whole opening period, and you can't officially release fish before the 20th, preferably above the 30th. Besides, you can't let the sun shine directly on the fish tank!

A In this article (), it is said that for fish or people who have filtering equipment and are qualified to use nitrifying bacteria, you can choose one of four methods. B In addition, after the tank is opened, the normal temperature of fish should be determined according to the species, survival and treatment of fish and aquatic plants. C after opening the fish tank, the fish tank should be illuminated, but not in direct sunlight. In addition, the living places of nitrifying bacteria such as filter tanks must be ventilated away from light (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. Do not soak in water, filter for 8 hours, trickle filter 12 hours. (c) Filling up with water does not mean filling up the tank mouth, but adding it to a suitable position. Generally, it is at a certain distance from the tank mouth, and the distance depends on the size and design of the tank.

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).

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, wash the filter cotton at the top of the filter tank with clear water (do not use detergent) (be careful not to change the biochemical cotton in the middle layer) by one sixth at a time. 10 Change water for 20 days in winter and 5-7 days in summer. Water needs to be changed under special circumstances, and special treatment should be carried out after cleaning the filter cotton. Therefore, the advantage of less fish in the tank is that it can change less water and balance the water quality in the tank.

5. Eat your food within 15 minutes. Take out the remaining bait once or twice a day. Don't feed the cheapest red and green grains in the fish shop, such as grass goldfish (red crucian carp), even the steamed bread you eat is better than that.

6. Be careful when using drugs, because almost all drugs are overdosed, and the fish will definitely die, even the commonly used salt. Therefore, we should pay attention to the dosage, early detection and early treatment. If an individual or a few people have problems, it is best to treat them in isolation. We must be careful when using drugs in three cylinders. Many people poison their fish with their own drugs. Third, in the process of treatment, the water temperature is sometimes appropriate and important.

Some people use water purification agents and fungicides indiscriminately in order to purify water. Here's a reminder: don't add drugs indiscriminately. Adding drugs illegally is like saying that the way to keep a person's room (without sewers and toilets) clean and not sick is to use fresheners, disinfectants and drugs. Do you think it's possible?

To purify water, it is necessary to strengthen the filtration system, strengthen the physical filtration of fine particles, strengthen the biological filtration to deal with harmful substances and purify water.

7. Some kinds of fish don't eat grass very much. If you want to grow aquatic plants, plant cheap and fast-growing black algae (Pteris vittata, Herba Sedi) and Sophora alopecuroides. Or Shui Rong, which is more expensive but grows slowly. Goldfish eat grass carp but don't eat big ones.

equipment

1. For large fish tanks or other things for holding fish, the standard is 10 cubic centimeter 1 cm of fish and thermometer.

(This is a must)

2. Appropriate filtering equipment is a good helper. For example, a good water tank is full, but there are few fish. It is not necessary to suggest the filter cotton for filtering (selecting) the first layer of filter residue. I use super filter cotton (if there is an upper filter screen, it is best to use it).

3. The suitable bottom sand is not quartz sand, nor is it black gold sand for special lovers. It is good to plant grass with a thickness of 3 to 4 cm (optional).

4. Some kinds of fish don't eat grass very much. For example, to grow aquatic plants, it is necessary to grow cheap and fast-growing black algae (Pteris vittata, water grass) and Sophora alopecuroides. Or aquatic plants in Shui Rong are expensive but grow slowly, and fish don't eat much, which is good for ecological balance. If conditions permit, they can be planted (recommended).

5. Three bacteria, used for cylinder opening and water purification. Nitrifying bacteria, yeast, lactic acid bacteria, active lactic acid bacteria (optional)

Or EM bacteria, is a microbial preparation composed of more than 56 kinds of microorganisms belonging to 6 genera, mainly including nitrifying bacteria, photosynthetic bacteria, lactic acid bacteria, yeasts, actinomycetes and so on. (optional)

6. Heating rods, tropical fish, goldfish and koi fish with room temperature below 22 degrees in winter (optional).

7. Lamps are not required if they can avoid direct sunlight and get enough light every day (recommended).

Buy fish

1. Don't choose thin and flat fish.

2. Don't choose fish with lesions (such as white (red) spots, white (red) spots, body deformity, scales, etc.). )

Don't choose fish without water.

Sunbathing, or name: dry water, trapped water (choose one). Pay attention to prevent pollution when drying.

Large-opening container made of nontoxic materials

1. Exposed to water in the sun for at least 1 day.

Second, there is no sunshine, in a cool and ventilated place, dry water for a week.

Three, the gas explosion more than 24 hours of water.

4. Illuminate a strong light near the water surface, and it will explode in half an hour.

Outbreak algae

Algae bloom is caused by excessive light or natural light. Reduce the illumination intensity to 0.5W per liter of water and the illumination time to 8 hours. It is best to turn on the lights for 3-4 hours in the morning and afternoon respectively. If the natural light is too strong, pay attention to shading! This process takes about half a month.

Adding algae-removing organisms such as black shell shrimp.

Green water is an algae bloom. Suggestion: 1. Add a piece of medical absorbent cotton to the filter tank, let the water filter from it, and then wash it after it is dirty (never use detergent or the like). Reduce the light to 6 hours. In addition, 3. Some netizens have done the water tank experiment of snails (not snails) with 10* 10 super green water filtering ability. You don't need it. You can still eat it. 4. The filter barrel with sterilization ultraviolet lamp can also solve this problem.

If you want fish to float, you are not afraid of being fed and drunk. You should starve the fish for a day or two first, and put one or two or three according to the number of fish when feeding. People have to wait until the fish is finished and feed it. Develop the habit of making fish not afraid of people, lovers and eating on water. Disadvantages: slow effect, but harmless to fish, more pleasing. Need 1 week or more. (Note that the feeding amount is still the usual amount, and you can't pass it. )
