The water quality problem of goldfish, the requirements of goldfish for water quality

You don't have a complete filtration system in place.

You also don't have nitrifying bacteria in the filtration system to help break down the substances in the water (proteins, nitrates, etc., a lot).

So your water will be more turbid (the water will definitely be turbid after feeding, food residues, fish body fluids, feces, will directly affect the water, and there are too many reasons that affect the water quality, so you have to cultivate nitrifying bacteria to help break down what you can't see, use filter cotton to filter visible impurities).

Let's not talk about what kind of water you use, tap water definitely doesn't work, you need to stand for 12-24 hours before you can use it, you need to wait for the chlorine to evaporate, so it won't cause harm to the fish.

At the same time, the fish breathe through the gills, and the gills flow through the gills to get the oxygen in the water, so you need to get oxygen to make sure that the water is rich in oxygen, so that the fish does not float and breathe.

Do not use tap water directly. Tap water is left on the balcony to dry for several hours. After that, wait for the water to change to room temperature. It is also possible to use clean rainwater.

Put clean tap water in the sun for two to three days before putting the fish in.

Use clean river water and avoid using undried tap water. Try not to use well water.

If you use tap water, you should dry it for 1 2 days first, or you can use pure water to tap water in a ratio of 1:3 for half a day.

1. Goldfish have a pH value in the water in the range, but they like neutral alkaline water quality, and pH is appropriate. Chloride ions in the water are also one of the factors that can cause goldfish poisoning death, so the tap water used for goldfish farming should be exposed to the sun for about 24 hours or left for 2 to 3 days before use, and baking soda can also be put in the water to remove chlorine flush slip ions.

2. Dissolved oxygen in the water is another important factor affecting the growth of goldfish, and its deficiency will cause slow growth and floating head of goldfish, and in severe cases, it will also cause death.

3. Goldfish is a wide-temperature fish, which has a wide range of adaptation to temperature, and can survive in the water temperature of 0 to 38 degrees Celsius. The most suitable is a lack of growing temperature of 20 to 28 degrees Celsius, when the water temperature exceeds 30 degrees Celsius.

Feeding too much causes the water to become cloudy. The amount of feed given to the goldfish needs to be controlled, and the muddy water needs to be replaced in time.

There are four types of water for goldfish farming:

New water, i.e. freshly dried tap water or freshly pumped well water. Although the water is clean, it is very different from the environment in which fish live in nature. Since there is no nitrifying bacteria community in the water, fish excrement and scattered food residues decompose into ammonia after deterioration, and fish are highly susceptible to poisoning.

The old water, light green and spike or light amber color, is rich in sapro-bridging and beneficial microorganisms and algae, and has established a good ecological circulation system, which is decomposed into nitrate that is harmless to fish through nitrogen cycling. This water is extremely beneficial for the growth of fish.

Green water, the organic matter content in the water is too much, so the cyanobacteria, green algae and brown algae multiply, the content of bacteria and microorganisms increases, the water is thick green, sometimes it will emit a foul smell, it is easy to cause the whole tank of fish to die.

Clear water is the green water with too much algae and microorganisms, which depletes the oxygen in the aquarium, causing the death of algae and aerobic bacteria, making the water extremely clear, without oxygen and with a large number of anaerobic harmful bacteria.

1. Filtration system. Installing a filtration system in a fish tank or pond can ensure effective water quality and remove small suspended impurities from the water. In particular, biofilters can decompose waste and reduce the presence of harmful substances.

2. Feed selection. When feeding goldfish food, we should pay attention to the choice of feed, otherwise it will affect the water quality, goldfish have a wide range of food choices, you can choose powder food, pellet food, nematodes, algae and blood bloodworms. However, these feeds are easy to affect the water quality, which is not conducive to the cleaning of the water and will cause suspended solids.

3. The density of the fish. Breeding goldfish also requires a certain density to ensure the activity of the fish, the fish can eat and pull, if the density is large, the growth of the fish will be affected, and it will also affect the water quality, so you should choose the container for feeding according to the situation.

4. Fish farming environment. Light has a certain effect on the growth of goldfish, and high-intensity exposure will affect the quality of the water, and will also cause a large number of algae to grow, so you can use curtains to cover and clean up regularly.

There are many reasons why goldfish always float on the surface:

1. The water quality is poor, and the amount of dissolved oxygen in the water is too low. When the fish feels difficult to breathe, it will stick its mouth out of the water and swallow the air to produce a floating head, so it should be replaced with new water;

2. Pathological reactions. Fish with gill disease often float their heads, which cannot be eliminated even if the water is changed, which requires medical treatment;

3. Low air pressure. Especially when the weather is hot or before it rains, the fish will also have a floating head, which requires the air pump to be started;

4. Kaiqiyun overeats. The fish will swim to the surface of the water and use the beam to help digest the air, a phenomenon that requires control of the amount of food.
