1. What is the correct way to raise fish in a cement pond?

1. First clean the fish pond according to its condition. The alkalinity of the newly made cement fish pond is too high. You can fill it with water and soak it for a week to dilute the alkalinity of the cement. Then drain the water, rinse it several times, and then add an appropriate amount of potassium permanganate for sterilization;

2. Then drain the water from the fish pond and let it air dry for three to five days. This will remove chlorine and raise the tap water to ambient temperature.

3. Add a few healthy and cheap small fish and observe the changes in the fish's state until the fish can breathe steadily, swim naturally, forage normally, and not sink to the bottom or float. This is a suitable living environment.

4. Finally, do not rush to put the fish into the pond. First, put the plastic bag containing the fish into the pond for ten to twenty minutes before opening it. Then let the pond water flow back into the bag several times and gradually mix with the original water in the bag, so that the fish can gradually adapt to the water temperature and water quality of the pond. If the fish are not of the same species, it is best to divide the fish pond into several small fish ponds for separate breeding, which is conducive to disease prevention and treatment.

2. What is the correct way to raise fish in cement ponds?

First, plan the size according to your needs

2. You don't need to choose cement with a high grade of 325 or 425. A small amount of sand is enough, but it is better to be thicker, 5 to 8 cm thick. The surface must be smooth enough. In addition, do not place the construction in a low temperature, otherwise it will easily cause the pool wall cement to crack.

3. Bricks do not require special materials, but they must be laid and stacked flat.

4. If you want to prevent water leakage, it is best to do a waterproofing after the cement wall is built. This can be done by professionals. It is not easy to do it yourself. Tell them that it is used to build a fish pond. They will choose non-toxic materials. Except for cement and waterproof materials, other things will not come into contact with the pool water. Cement itself will not cause any pollution to the pool water, but the pool wall still needs to be cleaned with aquatic special disinfectants and insecticides before use.

3. How to permanently de-alkali fish in cement ponds?

Slow de-alkali method: fill the newly built cement pool with clean water and soak it. Change the water every 2-3 days. After soaking for 15-20 days, the high alkalinity in the cement pool can be basically removed. When green moss grows on the pool wall or algae grows in the water, it can be used safely.

Vinegar soaking method: Fill the cement pool with clean water, then add vinegar to the pool water. Add 0.5 kg of vinegar per cubic meter of water. After soaking for 1-2 days, drain the water, clean the cement pool and fill it with new water.

Superphosphate method: Fill the cement pool with clean water, then add superphosphate or acidic sodium phosphate and phosphoric acid to the pool water. The dosage is 1 kg of superphosphate, 20 g of acidic sodium phosphate or 250 g of phosphoric acid per cubic meter of water. After soaking for two days, drain the water, clean the cement pool and inject new water.

The glacial acetic acid method is to use 10% glacial acetic acid to clean the bottom and walls of the newly built cement pool, then fill it with water and soak it for 3-5 days, then drain the water, clean the cement pool and replace it with new water.

The second method is to fill the cement pool with clean water, and then add glacial acetic acid to the pool water. The dosage is 10-20 ml of glacial acetic acid per cubic meter of water. After soaking for 2 days, drain the water, clean the cement pool and inject new water.

Alum neutralization method: Fill the cement pool with clean water, then add alum little by little until the water in the pool does not dissolve it. After soaking for 1-2 days, drain the water containing alum, clean the pool, and add new water.

Common methods for de-alkali softening include softened water acid treatment, lime method, lime-soda ash method, lime-calcium chloride method, ammonium-sodium ion exchange system, hydrogen-sodium ion exchange series system, chlorine-sodium ion exchange parallel system, chlorine-sodium series system, electrodialysis sodium ion exchange system, etc.

4. How to raise fish in a 5 square meter cement pond?

Before raising fish, you need to fill the pond with water for five days, then drain the water and fill it up again for ten days.

If you are not in a hurry to raise fish, it is best to soak the pond for a month until moss grows in the water, then drain the water and clean it before raising fish.

It is best to put some water lilies during the soaking period to allow them to absorb the toxic substances released by the cement. New ponds need to be soaked in water, otherwise the fish will not survive.
