5. Maintenance
Regular maintenance is crucial for a healthy aquatic environment:
- Water Changes: Perform partial water changes (25-30%) weekly or bi-weekly, depending on fish load and water quality. Always use dechlorinated water.
- Filter Sponge Cleaning: Rinse the reusable filter sponge weekly with old tank water (not tap water) to remove accumulated debris without destroying beneficial bacteria. Replace the sponge every 2-4 weeks or as needed.
- Pump Cleaning: Periodically disassemble and clean the water pump impeller and housing to prevent blockages and maintain efficient operation.
- Glass Cleaning: Use an aquarium-safe cleaner or scraper to remove algae from the tank walls.
- Feeding: Feed fish small amounts once or twice a day. Avoid overfeeding, which can lead to poor water quality.

6. Troubleshooting
Here are some common issues and their potential solutions:
- Cloudy Water:
Cause: New tank syndrome, overfeeding, insufficient filtration, or bacterial bloom.
Solution: Perform a partial water change, reduce feeding, ensure filter is clean and functioning, and allow time for the biological filter to establish. - Pump Not Working:
Cause: Power outage, clogged impeller, or airlock.
Solution: Check power connection, unplug and clean the impeller, or gently shake the pump to release air. - Lights Not Turning On/Changing Color:
Cause: Power issue, faulty switch, or incorrect button press.
Solution: Check power connection. For color change, ensure a gentle press on the button. For on/off, use a firm press. - Fish Showing Stress:
Cause: Poor water quality (ammonia, nitrite, nitrate spikes), incorrect temperature, or overcrowding.
Solution: Test water parameters, perform a water change, ensure heater (if used) is functioning correctly, and avoid overstocking the tank.
