Initial Setup Steps:
- Placement: Choose a stable, level surface away from direct sunlight and heat sources. Ensure the location can support the weight of the filled aquarium.
- Rinse Components: Rinse the ceramic media and the aquarium thoroughly with clean water. Do not use soap or detergents.
- Install Filtration: Place the ceramic media at the bottom of the aquarium, surrounding the central filter column. Insert the filter cartridge into its designated slot within the central column.
- Connect Air Pump: Connect the airstone to the air pump via the air line tubing. Position the air pump outside the aquarium, ensuring it is above the water level to prevent back-siphoning.
- Fill with Water: Carefully fill the aquarium with dechlorinated water. Use the provided water conditioner as directed to neutralize chlorine and chloramines.
- Add Beneficial Bacteria: Introduce the beneficial bacteria liquid to help establish the biological filtration.
- Install LED Light: Place the Standard LED light unit on top of the aquarium. Connect the 12V transformer to the LED light and the air pump, then plug it into a power outlet.
Introducing Fish:
It is crucial to allow your aquarium to cycle before introducing fish. This process establishes beneficial bacteria necessary for a healthy aquatic environment.

Operating Your biOrb Aquarium
Once set up, your biOrb aquarium operates continuously to maintain a healthy environment for your fish.
Lighting:
The biOrb CLASSIC 15 is equipped with a Standard LED Light unit. This low-voltage LED lighting provides illumination for your aquarium. It operates from the same 12V transformer as the air pump.

Feed your fish sparingly, only what they can consume within a few minutes, to prevent overfeeding and water quality issues.
Maintenance and Care
Regular maintenance is essential for a healthy and clear biOrb aquarium. The biOrb CLASSIC 15 utilizes a 5-stage filtration system for optimal water quality.

Troubleshooting
This section addresses common issues you might encounter with your biOrb CLASSIC 15 Aquarium.
Common Issues and Solutions:
- Cloudy Water:
This can be common in new aquariums as beneficial bacteria establish. Ensure proper filtration is in place and avoid overfeeding. Perform a partial water change if cloudiness persists. Check if the filter cartridge needs replacement.
- Reduced Air Bubbles:
Check the air pump for blockages or damage. Ensure the airstone is clean and not clogged. The air line tubing should be free of kinks.
- LED Light Not Working:
Verify that the transformer is securely plugged into both the light unit and the power outlet. Check for any visible damage to the light unit or wiring.
- Fish Showing Signs of Stress/Illness:
Immediately check water parameters (temperature, pH, ammonia, nitrite, nitrate). Perform a partial water change. Ensure the aquarium is not overcrowded and that fish are compatible. Consult a local aquatic pet specialist if symptoms persist.
