Pet Fishkeeping Fish Pond Water Quality Maintenance Guide
Fish keeping is not only a hobby, but also an art, especially in the home fish pond, the maintenance of water quality is crucial. Water quality directly affects the health, growth and reproduction of fish, therefore, mastering the skills of water quality maintenance is especially important for every fish lover. Below, we will detail how to effectively maintain the water quality of the pet fish pond.
#### I. Understanding water quality parameters
The first step in maintaining the water quality of the fish pond is to understand the basic parameters of water quality, including:
1. **pH value**: The pH of the water in the fish pond should usually be maintained between 6.5-7.5. Different fish species have different pH requirements, so care needs to be taken when selecting fish species.
2. **Ammonia (NH3-N)**: This is a harmful substance produced by fish metabolism, and the ideal value should be less than 0.2 mg/L. High concentration of ammonia will lead to fish poisoning. 3. **Nitrite (NH3-N)**: This is a harmful substance produced by fish metabolism.
3. **Nitrite (NO2-N)**: also a harmful substance, the ideal value should be 0 mg/L. Elevated nitrite is usually associated with an imbalance in the nitrogen cycle of the water body.
4. **Nitrate (NO3-N)**: relatively low toxicity, the right amount of nitrate to help plant growth, but the concentration should not exceed 20 mg / L. 5. **Dissolved Oxygen (NO2-N)**: also a harmful substance, the ideal value should be 0 mg / L.
5. **Dissolved Oxygen (DO)**: Fish need oxygen to survive, and the ideal value of dissolved oxygen in water should be more than 5 mg/L.
#### II. Regular water quality testing
In order to maintain stable water quality, it is recommended to test the above parameters regularly with a water quality testing kit (e.g. test paper or water quality tester). Test at least once a week so that problems can be detected and measures taken in time.
#### iii. Maintain water circulation
Water circulation is an important part of maintaining water quality. It can be realized by the following ways:
1. **Installation of water pumps**: water pumps can promote water circulation, increase the mobility of the water body and prevent the generation of stagnant water areas.
2. **Filtering systems**: the use of filters removes impurities, feces and residual food from the water while aiding in the nitrogen cycle.
3. **Oxygenation equipment**: Installing oxygenators or air pumps in the water can increase the oxygen content of the water and promote the growth of fish.
#### IV. Rational feeding
Overfeeding is one of the main causes of water quality deterioration. The following principles should be followed:
1. **Moderate feeding**: According to the number and size of fish, the feeding amount should be reasonably calculated, and it is generally recommended that each feeding should not be more than 2-3% of the fish's body weight.
2. **Fixed-time and fixed-point**: Establish a fixed feeding time and place to avoid deterioration of water quality due to food grabbing by fish.
3. **Choose high-quality feed**: High-quality feed can reduce the production of fish excreta and control water quality pollution at source.
#### V. Replace part of the water body regularly
Regular replacement of part of the water body can effectively dilute the harmful substances in the water. It is recommended to replace 10%-20% of the water every week. Replacement should be noted:
1. **Similar water temperature**: The temperature of the newly added water should be similar to the water temperature of the fish pond so as not to cause fish stress.
2. **De-chlorination treatment**: Tap water usually contains chlorine, and de-chlorination treatment is required when using it, either by using chlorine remover or letting the water stand for 24 hours.
#### VI. Add aquatic plants
Aquatic plants not only beautify the fish pond, but also provide oxygen and absorb nutrients in the water through photosynthesis, reducing nitrogen and phosphorus levels. Common aquatic plants include duckweed, lotus and water onion.
#### VII. Clean the fish pond regularly
Keeping the fish pond clean is an important part of maintaining water quality. Regularly clean the bottom of the fish pond of sediments, residual feed and weeds to prevent the accumulation of organic matter. At the same time, you can regularly replace the filter cotton and clean the filter to ensure the normal operation of the filtration system.
### Conclusion
Fish farming is an activity that requires patience and care. Maintaining good water quality is the foundation for ensuring healthy fish growth. By regularly testing the water quality, keeping the water circulating, feeding properly and cleaning the fish pond, you can effectively improve the water quality of your fish pond and ensure that your pet fish live in a healthy environment. We hope these suggestions will help every fish lover to make your fish pond more vibrant!
