How to change the water in a fish tank The correct way to change the water in a fish tank

1. Use a clean basin first, fill it with water, and leave it for 1-2 days, so as to facilitate the volatilization of chlorine in the tap water, so as not to affect the health of the fish. Mul.

2. After the water is left for a period of time, then use a water jug to put two-thirds or half of the water in the fish tank into a clean container. Mul.

3. Take out the stones in the fish tank and brush them. Then pick up all the small fish and shrimp in the fish tank with a drain net and put them in the container of 2 steps. Mul.

4. After all the fish and shrimp are fished, the fish tank can be thoroughly cleaned. Mul.

5. After the fish tank is cleaned, slowly put the water and fish and shrimp in the 2-step bucket in the cleaned fish tank, slowly add the water placed in the first step into the fish tank, and then place the stones to complete the water change, and the fish will have a clean environment.

To change the water in the fish tank, it is best to drain the water by siphon method. It is enough to change 2 3 water at a time, and tap water needs to be exposed to the sun for three days before it can be changed.

Not so complicated, simple. Scavengers and other tropical fish cannot be polycultured with small carp. And the tank is so small, the scavenger is also very aerobic.

Your koi fish are not moving now, perhaps because the tank has been changed with water, or because your tank is too narrow. The little koi is easy to raise, and the oxygen demand is not high, so you may not need your inflatable lei, but it also depends on the number of koi you have. But koi fish is really not suitable for deep tank raising, because of the body length, and the number moves, like to swim, the deep tank will make it can only move up and down, very uncomfortable, you would rather buy a size to adapt to the round glass tank raising, very small koi can even use the disc tank.

If the water is not dirty, change it half at a time, change it once a day (I don't know how big your tank is, you can find out the water change time by yourself) and change it all if it is dirty. Koi fish are really easy to raise, and they have strong adaptability, and it is not a problem how much they are fed, and they are very edible and cannot die. The main thing is that if you don't want to change the water too much, you can feed it less.

But the bigger koi will like to jump the tank, and you can pay attention to the height of the water level. Koi fish are also not easy to get sick and have strong vitality, but the environment should try to let them adapt to it, if you feel really sick as the upstairs said, go to the flower and bird market to buy a bottle of blue potion and drop it in the tank, and it will be fine soon.

If you are used to keeping fish, you can go directly to the tap water.

If filtered, once a week, a quarter to a third of a time.

Fishing. Pour the water.

Change the water. Put the fish.

1. On the day before the water change, store enough fresh water to replace the amount of fresh water, the purpose is to release the chlorine in the fresh water, because we use chlorine to disinfect our own drinking water. If you need it, you can store fresh water two or three days in advance, and some friends will even use gas wood or gas stones to pump water in fresh water, or add submersible pumps to make water flow to speed up gas exchange.

2. Before changing the water, add a sufficient amount of sea salt to the freshwater stored in advance, and then stir to completely dissolve the salt particles. The specific gravity of the new water is measured by the specific gravity, and the specific gravity is best consistent with the fish tank water. If necessary, the fresh water can be mixed with salt two or three days in advance, and a submersible pump can be added to make a water flow to completely dissolve the salt particles and enhance the dissolved oxygen content of the new seawater.

3. When changing the water, first pump the old seawater that needs to be replaced from the fish tank, and then slowly add the new seawater to the fish tank, do not pour all the new water into the fish tank, and avoid the remaining undissolved salt particles from entering the fish tank to make a shock to the organisms. If there is a sand tank, the water change process should be carried out in the sand tank.

<>1. First of all, the water temperature and pH value and water hardness should be adjusted, and the water temperature of the new water and the old water should be as consistent as possible.

2. Prepare a small bucket, use a water suction device to suck up the water at the bottom of the fish tank, and by the way, suck away the fish feces, residual feed, garbage, etc. at the bottom of the fish tank, so as to achieve the purpose of cleaning the bottom of the fish locust tank.

3. When the water is absorbed to the preset amount of water, you can pour new water into the fish tank, and the new water should be poured slowly along the fish tank wall in batches, not poured all at once, and it is especially important to pay attention to the new water to avoid washing on the fish body, and try to avoid damaging the water quality environment in the original fish tank.

1. Unplug all power plugs of insulation, filtration, oxygenation, lighting and other systems on the fish tank.

2. Drain the water in the fish tank so that the water in the aquarium is about one-half.

3. Gently fish the fish into a container filled with fresh water that is similar to the original water temperature and prepared in advance, and put it into the aeration pump to increase oxygen to prevent the water change time from being too long and the fish from hypoxia.

4. Pump out all the remaining water in the fish tank, take out the filter, electric heating pipe, pebbles, aquatic plants, etc., and clean and disinfect them.

5. First scrub the aquarium around with clean water, then soak and rinse the fish tank with a small amount of concentrated salt water or potassium permanganate solution, and then rinse the fish tank with clean water after disinfection.

6. After the fish tank is completely cleaned, you can put sand, stone and other landscaping materials into the fish tank to arrange, after the layout, add about one-third of the new water, and then plant aquatic plants in the fish tank.

7. After installing the oxygen pump, thermometer, electric heating pipe and filter device, add two-thirds of the new water to the fish tank.

8. Start all power equipment, and when the water temperature reaches the requirements, carefully fish the ornamental fish into the fish tank with a fishing net.
