What should I do with water and fertilizer in the fish tank? Comprehensive analysis of causes and solutions
Recently, many aquarists have been hotly discussing the issue of "water and fertilizer in fish tanks" on social platforms and forums, especially as high temperatures in summer have aggravated the eutrophication of water bodies. This article will combine the popular discussions on the Internet in the past 10 days to provide you with structured data and practical suggestions from causes, hazards to solutions.
1. Common causes of water and fertilizer in fish tanks

| Reason type | Specific performance | Proportion (based on discussion popularity) |
|---|---|---|
| Overfeeding | Remaining bait accumulates and decomposes to produce ammonia nitrogen | 35% |
| Insufficient filtration system | Low physical or biochemical filtration efficiency | 28% |
| Too much light | Explosive algae blooms | 20% |
| Frequent water changes | Accumulation of harmful substances | 17% |
2. The harm of water and fertilizer (data comes from recent feedback from aquarists)
| Hazard type | Symptoms | Urgency |
|---|---|---|
| fish hypoxia | Floating head, shortness of breath | high |
| algae bloom | The water is turbid and covered with green algae | in |
| Germs breed | White spots or ulcers appear on the fish body | high |
3. Solutions and practical steps
1. Adjust feeding habits
The daily feeding amount should be controlled so that the fish can eat it within 2 minutes, and the remaining bait should be fished out in time. The low-pollution formula recently launched by the popular fish food brand "XXX" has been recommended many times.
2. Upgrade the filtration system
| Filter type | Applicable scenarios | Recommended products (hot TOP3) |
|---|---|---|
| Physical filtering | More particulate matter | A certain brand of wool filter cotton |
| biochemical filtration | Ammonia nitrogen exceeds the standard | A certain brand of ceramic ring |
| UV germicidal lamp | Algae/Bacteria Problems | A certain brand of portable UV lamp |
3. Control light and change water
The daily lighting should not exceed 8 hours, and a timer can be used. Recommended frequency of water changes: 1/3 per week for small tanks and 1/4 every two weeks for large tanks. A recent blogger’s actual measurement showed that using a water quality stabilizer can reduce the stress of water changes.
4. User test cases (from recent popular posts)
Case 1: The aquarist "Shui Qing Yu Liang" improved his water and fertilizer problems by 80% in 3 days by reducing feeding and increasing filter materials.
Case 2: After using UV lamp, the algae problem was significantly relieved within 24 hours, but care should be taken to avoid irradiating fish.
Summary
Fish tank water and fertilizer need to be managed comprehensively. Reducing pollution sources from the source and strengthening filtration are key. If the problem persists, it is recommended to use a water quality detector (sales on an e-commerce platform recently increased by 120%) for precise control. Only with patience and regular maintenance can you achieve your "air cylinder" goal!
