| Ammonia | 0 | Gill damage, breathing difficulty |
| Nitrite | 0 | Oxygen transport issues, lethargy |
| Nitrate | < 20 | Stress, weakened immunity |
Effective Filtration Methods
Good filtration reduces harmful chemicals and keeps water clean. Use filters that support both mechanical and biological cleaning.
- Mechanical filters remove solid waste and debris.
- Biological filters use bacteria to convert ammonia and nitrite into nitrate.
- Regular filter maintenance prevents clogging and keeps the system working well.
- Use activated carbon to absorb toxins and impurities.
- Perform frequent partial water changes to lower nitrate levels.
Water Change Schedule
Keeping your guppy tank water clean is key to their health. Regular water changes remove waste and keep water safe.
Setting a good schedule helps maintain water quality and keeps your guppies happy.
Frequency And Volume
Change water often to avoid harmful toxins. Usually, change 25% to 30% of the water each week.
For tanks with many guppies, increase water changes to twice a week. Smaller tanks may need more frequent changes.
- Weekly: Change 25%–30% of the water
- Busy tanks: Change 30% twice a week
- Small tanks: Consider more frequent changes
Tips For Stress-free Changes
Water changes can stress guppies if done too fast. Use gentle methods to keep fish calm.
Match the new water temperature and add conditioner to remove chlorine. Move water slowly during changes.
- Use a water conditioner to remove chlorine
- Match the new water temperature to the tank
- Pour water slowly to avoid disturbing fish
