Setup Guide
Follow these steps to set up your VIVOHOME Smart Fish Tank:
- Prepare the Tank: Carefully unbox all components. Rinse the glass tank body, filter modules, and any decorations thoroughly with clean water. Do not use soap or detergents.
- Install Filtration: Place the bio filtration module and mechanical filtration modules into the back filter compartment. Ensure they are seated correctly.
- Add Substrate and Decorations: Place your chosen substrate (gravel, sand) at the bottom of the tank. Add any desired decorations or live plants.
- Fill with Water: Slowly fill the tank with dechlorinated water to the recommended level, leaving a small gap from the top rim.
- Connect Pump and Power: Install the water pump into its designated slot in the filter compartment. Connect the power adapter to the tank and then to a power outlet.
- Initial Cycling: Run the filter for 72 hours to 1 week or more to establish beneficial bacteria for a healthy aquatic environment. Add nitrifying bacteria as recommended by aquarium experts.
- Test Water: Before adding any fish, test the water parameters (ammonia, nitrite, nitrate, pH) to ensure they are safe for aquatic life.
- Add Fish: Introduce fish gradually after the tank has been properly cycled and water parameters are stable.

Cleaning and Water Changes
- Perform regular partial water changes (e.g., 25% weekly) to maintain water quality.
- Rinse filter media periodically with old tank water to remove debris without killing beneficial bacteria. Replace filter media as needed, typically every 2-4 weeks.
- Clean the tank glass with an aquarium-safe cleaner or magnet cleaner to remove algae.
Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Automatic feeder dispenses too much food. | Feeder mechanism may not be calibrated for very small pellets or flakes, or settings are too high. | Adjust feeding frequency or portion size in the app. Consider using larger pellets or flakes if possible. Monitor initial dispenses to fine-tune. |
| App lighting schedule is basic (ON/OFF only). | Current app functionality may limit advanced lighting schedules. | Utilize the available ON/OFF schedule. For more complex lighting cycles, manual adjustment or external timers may be required. Check for app updates. |
| Tank power not working. | Loose power connection, faulty adapter, or power outage. | Check all power connections. Ensure the adapter is securely plugged into both the tank and the wall outlet. Test the outlet with another device. Contact customer support if the issue persists. |
| Filter inlets may suck up small fish/shrimp. | Inlets are not fine enough for very small aquatic life. | Consider adding a pre-filter sponge over the filter inlets to protect small inhabitants like shrimplets. |
| Display panel peeling off. | Adhesive issue or manufacturing defect. | Gently press the panel back into place. If it continues to peel or affects functionality, contact customer support for assistance. |
