The correct methods of conditioning water for koi fish mainly include the following:
Sunlight Exposure Method: Expose the water to the sun for 24 to 48 hours, which can effectively remove chlorine in the water and kill parasites such as Ichthyophthirius multifiliis. But be careful not to expose it for too long, otherwise bacteria will easily multiply.
Heating and Aeration Method: Use a heating rod to adjust the water temperature to the maximum, and then put in an oxygen pump to aerate for 2 hours. This method can not only sterilize but also increase the oxygen content in the water, which is especially helpful for the growth of fish.
Fish Le Bao Method: Add Fish Le Bao according to the instructions before changing the water, and use it after it is completely dissolved. This method is simple and convenient, but pay attention to the dosage to avoid overdose.
Water Purifier Method: Use a water purifier with an RO membrane to filter water. This method can provide very pure water quality and is suitable for directly raising fish. However, it should be noted that the water purifier should be cleaned regularly to maintain the water cleanliness.
Water Quality Treatment and Water Change Skills after Conditioning Water:
Water Change Frequency: Generally, change one-fifth to one-third of the water every three to four days. The specific frequency is determined according to the water quality of the fish pond.
Oxygenation Equipment: Koi fish have a high demand for oxygen, especially in the fish tank, oxygenation equipment is more needed to improve the living environment.
Water Temperature Control: When changing the water, control the temperature difference between the new water and the old water within two to three degrees to avoid excessive temperature difference from irritating the fish.
Water Quality Monitoring: Regularly conduct water quality monitoring to avoid excessive concentrations of nitrate and ammonia nitrogen in the water.
Filtration System: Strengthen the filtration system, including physical, biochemical and plant filtration. Regularly clean the filter materials and add nitrifying bacteria.
Through the above methods, the water quality can be effectively treated and monitored to ensure the healthy growth of koi fish.
