How to raise water for guppies
Guppies are the first choice of many aquarium enthusiasts because of their brilliant colors and lively habits. However, for guppies to grow healthily, water quality management is key. This article will introduce in detail how to raise water scientifically to ensure that guppies thrive.
1. Water quality parameter requirements

| parameters | ideal range | Remarks |
|---|---|---|
| water temperature | 24-28℃ | It is easy to get sick when the temperature is below 20℃, and it is hypoxic when the temperature is above 30℃. |
| pH value | 6.5-7.5 | Weakly acidic to neutral is best |
| Hardness(GH) | 8-12 dGH | Too soft water affects bone development of fish |
| Ammonia/nitrite | 0mg/L | Toxic, requires regular testing |
| Nitrate | <20 mg/L | Change water to control concentration |
2. Detailed explanation of water maintenance steps
1. Water source selection:It is recommended to use aerated tap water or RO water and avoid directly using untreated well water or rainwater.
2. Dechlorination treatment:Tap water needs to be left standing for 24 hours or water quality stabilizer should be added to eliminate the harm of chlorine to fish.
3. Establish a nitrification system:The new tank needs to cultivate nitrifying bacteria. The method is as follows:
| stage | Operation | duration |
|---|---|---|
| Early stage | Add nitrifying bacteria preparation | 1-2 days |
| medium term | Feed in small amounts and monitor water quality | 3-7 days |
| stable period | Normal water change maintenance | long term |
3. Daily maintenance skills
1. Water change frequency:Change 1/3 of the water volume every week, and increase it to 2 times a week in summer or high-density breeding.
2. Filtration system:It is recommended to use a sponge filter or an external filter bucket to keep the water flow clean and oxygenated.
3. Disease prevention:Add coarse salt (1-3g/L) or yellow powder once a month to prevent white spot disease and saprolegnia.
4. Frequently Asked Questions
| question | Reason | solution |
|---|---|---|
| fin ulcer | Deterioration of water quality or bacterial infection | Water change + antibiotic bath |
| Guppies sink to the bottom and remain motionless | Water temperature is too low or ammonia poisoning | Raise temperature to 26°C + emergency water change |
| dull body color | Nutritional deficiencies or pH fluctuations | Replenish live bait and stabilize water quality |
5. Summary
The core of raising guppies well is"Steady water"——Keep water quality parameters stable, perform regular maintenance, and closely observe the status of fish. Through scientific management, your guppies will show their most brilliant colors and vitality!
