Setup Instructions
- Clean the Tank: Rinse the glass tank and all included components with clean water. Do not use soap or detergents, as residues can be harmful to fish.
- Position the Tank: Place the tank on a flat, sturdy surface capable of supporting the weight of the tank when filled with water and decorations. Ensure it is away from direct sunlight and heat sources.
- Install Filter Media: Place the provided filter cotton into the designated filter compartment. Ensure it is properly seated to allow for efficient water flow.
- Add Substrate and Decorations: If desired, add a layer of aquarium-safe substrate (gravel or sand) and decorations. Rinse these thoroughly before adding them to the tank.
- Fill with Water: Slowly fill the tank with dechlorinated water to the recommended level, typically just below the filter outflow. Use a water conditioner to remove chlorine and chloramines.
- Connect Power: Plug in the filter pump and LED light. Ensure all electrical connections are dry and secure.
- Cycle the Tank: Allow the filter to run for at least 24-48 hours before introducing fish. For a healthy aquarium, it is recommended to perform a nitrogen cycle, which can take several weeks. Research "aquarium nitrogen cycle" for more details.

Operating Instructions
Filter System
The integrated filter system is designed for continuous operation to maintain water clarity and quality. It creates a self-circulating water flow, reducing the frequency of water changes. Ensure the water level is always sufficient for the pump to operate effectively.

LED Plant Light
The LED light provides illumination for viewing and supports photosynthesis for live aquatic plants, contributing to oxygen production in the aquarium. The light can be turned on/off as needed. For optimal plant growth, a consistent light cycle (e.g., 8-10 hours per day) is recommended.

Maintenance
Regular maintenance is crucial for the health of your aquatic pets and the longevity of your aquarium.
- Water Changes: Perform partial water changes (25-30% of the tank volume) weekly or bi-weekly, depending on the bioload. Always use dechlorinated water that is temperature-matched to the tank water.
- Filter Cotton Replacement: The filter cotton should be rinsed weekly during water changes and replaced every 2-4 weeks, or as needed, to maintain optimal filtration. Do not replace all filter media at once, as this can remove beneficial bacteria.
- Tank Cleaning: Use an aquarium-safe scraper or magnet cleaner to remove algae from the glass surfaces. The tank's design may make reaching all areas challenging; use appropriate tools for thorough cleaning.
- Equipment Check: Periodically check the filter pump and LED light for proper function and any signs of wear.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Water is cloudy | New tank syndrome (bacterial bloom), overfeeding, insufficient filtration, dirty filter media. | Perform a partial water change. Reduce feeding. Rinse or replace filter cotton. Ensure proper tank cycling. |
| Filter pump not working or weak flow | Clogged impeller, low water level, power issue, pump malfunction. | Unplug and clean the impeller. Ensure water level is adequate. Check power connection. If still not working, contact support. |
| Tank is leaking | Seal failure, crack in glass. | Immediately drain the tank to prevent further damage. Inspect for visible cracks or seal issues. Contact customer support for warranty claims. |
| Excessive noise from filter | Air trapped in pump, impeller obstruction, pump vibration. | Gently shake the filter to release trapped air. Clean the impeller. Ensure the pump is securely mounted and not vibrating against the tank. |
