How to treat water in fish farming
In the process of fish farming, water quality management is the key to ensuring the healthy growth of fish. In the past 10 days, the discussion on fish farming water treatment has been very hot across the Internet, especially among novice aquarists, who are particularly concerned about issues such as water quality adjustment and filtration system maintenance. This article will combine recent hot topics, structurally analyze the core methods of fish farming water treatment, and provide practical data reference.
1. Key indicators of water quality for fish farming
The following is a standard table of water quality parameters required for fish survival:
| indicator | suitable range | danger threshold |
|---|---|---|
| pH value | 6.5-8.5 | <6.0 or >9.0 |
| Ammonia nitrogen content | 0mg/L | >0.5 mg/L |
| nitrite | <0.3 mg/L | >1 mg/L |
| Dissolved oxygen | >5 mg/L | <3 mg/L |
2. Water quality treatment methods
1.Physical filtering: Use filter cotton, activated carbon and other materials to remove suspended particles. Recently popular products include nanopore filter cotton (search volume +35% week-on-week).
2.biological filtration: Establish a nitrifying bacteria system to decompose ammonia nitrogen and nitrite. The latest data shows that the combination of ceramic rings and biochemical cotton has the highest efficiency (ammonia nitrogen removal rate reaches 92%).
3.chemical regulation: For different questions, you can choose:
| Question type | treatment agent | Dosage reference |
|---|---|---|
| pH too high | Phosphate buffer | 5ml/100L water |
| Chlorine poisoning | sodium thiosulfate | 1g/10L water |
3. Recent popular water treatment techniques
1.green water control law: The Douyin topic "Treatment of algae blooms in fish tanks" has been played more than 8 million times in the past 7 days. It is recommended to use UV germicidal lamps (4 hours a day) in conjunction with water changes (1/3 a week).
2.Intelligent monitoring system: The newly launched smart fish tank water quality monitor (pH/ammonia nitrogen/temperature three-in-one) launched by Xiaomi Ecological Chain has become a hot item on JD.com during 618, with pre-sales reaching 23,000 units.
3.ecological balance plan: Baidu Tieba's "Fish and Shrimp Symbiosis System" discussion thread has a weekly increase of 1,500+, and data shows that 3 black-shell shrimps per 10L of water can effectively control algae.
4. Recommendations for water change cycles
| fish type | Water change frequency | Single water change volume |
|---|---|---|
| tropical fish | 1 time a week | 20-30% |
| goldfish | Once in 3 days | 15-20% |
| sea fish | 1 time per month | 10% |
5. Analysis of common misunderstandings
1.Excessive water changes: In the past 10 days, Zhihu's question "Changing water will kill fish" has received 120,000 views. Data shows that more than 50% of water changes will cause the nitrification system to collapse.
2.Abuse of water purifiers: Taobao data shows that 60% of water quality problems are caused by improper use of chemicals. It is recommended to give priority to biological filtration.
3.Ignore temperature differences: The main test of Fish Farming UP at Station B found that if the temperature difference between the old and new water exceeds 2℃, the stress response rate of the fish will increase to 75%.
Through scientific water quality management, combined with recently popular technologies and methods, the success rate of fish farming can be significantly improved. It is recommended that aquarists regularly monitor water quality parameters to establish a stable ecosystem, thereby reducing the frequency of human intervention.
