3. Setup Instructions
Follow these steps to set up your fishkeeper Nano Aquarium:
- Unpack and Inspect: Carefully remove all components from the packaging. Inspect the aquarium and accessories for any damage.
- Choose a Location: Place the aquarium on a flat, stable surface away from direct sunlight, heat sources, and drafts. Ensure the surface can support the weight of the filled aquarium (approximately 12.5 kg or 27.5 lbs when full).
- Rinse Components: Rinse the aquarium, artificial plants, and filter sponge thoroughly with clean water. Do not use soap or detergents.
- Install Filter and Pump: The pump and filter system are pre-installed. Ensure the filter sponge is correctly seated within the pump housing.
- Add Substrate and Decorations: If using your own substrate (gravel, sand), rinse it thoroughly before adding it to the tank. Arrange the artificial plants and any other decorations.
- Fill with Water: Slowly fill the aquarium with dechlorinated water to the recommended level. Use a water conditioner to remove chlorine and chloramines.
- Connect Power: Connect the 5V power adapters to the appropriate ports on the aquarium unit and then plug them into a power outlet.
- Initial Cycle: Allow the aquarium to run for at least 24-48 hours before introducing any fish. This allows the filter to begin establishing beneficial bacteria. For a proper nitrogen cycle, refer to advanced aquarium cycling guides.

5. Maintenance
Regular maintenance is crucial for a healthy aquatic environment, even with the self-cleaning features.
5.1. 4-in-1 Self-Cleaning Circulation Ecosystem
The multi-functional pump integrates filtration, ventilation, gentle water movement, and circulation. This system helps minimize maintenance by absorbing impurities from the bottom and providing a rainfall filter outlet.
- Filtration: The filter sponge removes physical debris from the water.
- Oxygenation: The oxygen bubble outlet ensures adequate aeration for your fish. The bubble flow can be adjusted.
- Circulation: Gentle water movement prevents stagnant areas and distributes heat and nutrients.

5.2. Filter Sponge Cleaning and Replacement
The filter sponge should be rinsed weekly during water changes and replaced every 2-4 weeks, depending on the bioload of your aquarium. Rinse the sponge in old aquarium water to preserve beneficial bacteria.
5.3. Water Changes
Perform a partial water change (20-30% of the tank volume) weekly. This removes nitrates and replenishes essential minerals. Always use dechlorinated water at a similar temperature to the aquarium water.
5.4. Aquarium Cleaning
Wipe down the inside and outside of the aquarium glass as needed to remove algae and water spots. Use an aquarium-safe cleaning tool for the inside. Avoid using household cleaners on or near the aquarium.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power / Lights Off | Power adapter unplugged, power outage, faulty connection. | Check all power connections. Ensure the power outlet is functional. Contact support if the issue persists. |
| Pump Not Working | Pump clogged, impeller jammed, power issue. | Unplug the pump, remove it from the tank, and clean the impeller and housing. Ensure no debris is blocking it. Reconnect power. |
| Water Cloudy | New tank syndrome, overfeeding, insufficient filtration, bacterial bloom. | Perform a partial water change. Reduce feeding. Ensure filter sponge is clean and functioning. Allow time for the biological filter to establish. |
| Humidifier Not Producing Mist | Water level too low in humidifier compartment, clogged mist outlet. | Refill the humidifier water compartment. Gently clean the mist outlet to remove any mineral buildup. |
