Don't put any medicine. Keeping water well is the premise. Rich people can buy some nitrifying bacteria and put them in advance. The specific operation is as follows:

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! ), depending on the quality of food.

Measure, handle gently, use drugs with caution, and stay 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. The cylinder at least

More than 30 cm, it is easy to maintain water quality. Or if there is no filtering equipment, please calculate the length of fish and tropical fish per centimeter (excluding tail) according to the water surface area.

Fin needs 30 square centimeters of water, and goldfish needs 60 square centimeters.

2. Open the water tank to lift water. After being disinfected with strong brine, it is rinsed with clear water without residue, and then injected with water to enter the stage of water conservation. The water temperature in the water tank should be

Between 28 and 30 degrees (the temperature of cold water fish should not be lower than 15 degrees), after 7 days of hydroponics,

Or add nitrifying bacteria for 7 days every day after entering the fish tank for 3 days, and pay attention to avoid light) (

Bacteria) open the tank, but pay attention to the moderate weight, rather less than more, pay attention to avoid light and gas, and release the fish in the tank three days later) (

Soak the peeled raw shrimps in the water in the filter tank until the shrimps are completely melted. If there is filtration in the whole cylinder opening process, it will not stop for 20 days.

It is best to put fish for more than 30 days. Besides, you can't let the sun shine directly on the fish tank!

A () < 2 > in this paper; & lt3>& lt4> means that one of the four methods is enough for fish or people who have filtering equipment and need to use nitrifying bacteria conditionally.

B In addition, the normal temperature of fish after tank opening depends on the species, survival and treatment of fish and aquatic plants. C after opening the cylinder, there should be a fish tank.

Light, but not direct sunlight. In addition, places where nitrifying bacteria live, such as filter tanks, must be ventilated from light (if it is an internal filter or an external 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. If the water is not soaked, it will be filtered up for 8 hours and trickled up 12 hours) C plus.

Full water does not mean to fill the tank mouth with water, but to a suitable position, usually at a certain distance from the tank mouth, depending on the size and design of the tank.

Specifically.

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 the bag, put the naked fish into the tank, and add it into the bag several times during the period.

Put water in the tank to make the fish adapt to not feeding on the first day (pay attention not to have white spots, white hairs, rotten fins and scales on the fish when buying)

Changing water depends on your water quality. If there is a filter, the water tank is large or small, if there is no filter, the water tank is small or large, so it is necessary to dry the water and replace it.

Wash the filter cotton in the top layer of the filter tank with clean water (don't use detergent) (be careful not to change the biochemical cotton in the middle layer) for one sixth at a time. winter

10 to about 20 days, and change water in 5 to 7 days in summer. Water needs to be changed under special circumstances, and special treatment should be carried out after cleaning the filter cotton. So the advantage of putting a big fish in a jar is that

It can change water less and balance the water quality in the cylinder.

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 granules in the fish shop without oil, such as

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. So for medicine, the first thing is

Pay attention to the quantity, and the second is early detection and early treatment. If there are individual or few problems, it is best to treat them in isolation. We must be careful when using drugs in three cylinders.

Be careful, many people poison their own fish. 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 indiscriminately is like saying: take a gear.

The way to keep the room clean and not sick (without sewers and toilets) is to use fresheners and 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 plant aquatic plants, plant cheap and fast-growing black algae (Pteris vittata, water grass).

Swallowwort or Shui Rong, which are more expensive but grow slowly, goldfish and the like 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, the water quality is good, there is more water in the tank but less fish, so it is not recommended to filter (select) the first layer.

I use a filter cotton with super filter cotton as filter residue (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 (choose)

Use)

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 and can be planted if conditions permit (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 compound multi-strain nitrifying beneficial bacteria group, which mainly includes six kinds of nitrifying bacteria: photosynthetic bacteria, lactic acid bacteria, yeast and actinomycetes.

A microbial preparation consisting of more than 56 kinds of microorganisms belonging to a genus. (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 light intensity to 0.5W per liter of water and the light time to 8 hours, preferably with an interval of 3-4 hours in the morning and evening.

Turn on the light. 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 medical absorbent cotton to the filter tank, let the water filter from it, clean it after it becomes dirty, and then filter it (

Never use detergent or anything like that. Reduce the light to 6 hours. In addition: 3. Some netizens tried to filter green water with snails (not snails).

The super powerful 10* 10 tank takes about 2-4 hours, and 5 or 6 snails are enough. You can play a pot of green water and put a catty of snails first. No, it doesn't matter.

Go to eat. 4. The filter barrel with sterilization ultraviolet lamp can also solve this problem.
