Product Overview

1. 3-in-1 Filter Cartridge

Features:

• Efficient Filtration: Our unique waterfall design not only oxygenates the water, promoting healthier and more active fish, but also minimizes splashing, ensuring a remarkably quiet return.

• Adjustable Flow: Tailor the flow to accommodate bettas, shrimp, or plants that require lower flow rates without sacrificing filtration performance.

Identifying Strong Flow:
If the water flow is too forceful for delicate species like bettas or goldfish, they may exhibit signs of stress by struggling to swim freely or by huddling in specific areas.

No-Mess Filter Cartridge Changes:
Enjoy hassle-free maintenance with our fully assembled cartridge that combines biological, mechanical, and chemical filtration. It slides out effortlessly for quick maintenance and customization according to your needs.

Pre-Filter Sponge:
This sponge serves to prevent small fish and shrimp from being sucked in and purifies waste chemicals in the water, providing a safe environment for your fish. It enhances mechanical filtration, extending the lifespan of your filter media.

Leveling Knob:
This adjustment tool ensures the filter remains properly leveled against the tank, preventing spillage due to extreme angles.

Patent-Pending Priming System:
In the event of a power interruption, the filter will automatically restart upon restoration.

Troubleshooting Filter Issues:
If your filter ceases to operate, check for any impeller clogs. To resolve this:
1. Use tweezers to remove the impeller gently.
2. Rinse it under water.
3. Clear the impeller chamber.
4. Replace the impeller, and manually rotate to ensure it moves freely and primes the filter.

Installation Notes

Fitting on Framed Tanks:
To fit the intake tube on a tank rim, gently pull it into place. Note that it is suitable for framed or frameless aquariums up to 0.4 inches thick.

Important Setup Info:
Ensure to fill the filter with water before powering it on, as the pump should never run dry. Keep the water level in the tank no more than one inch below the aquarium rim.

If Priming Fails:
Double-check that all components are installed properly and securely. Fill both the filter case and fish tank as completely as possible, ensuring the flow control valve is firmly attached in the maximum flow position.

Addressing Noise Issues:
To reduce filter noise, adjust the leveling knob to decrease vibration. Make sure air is evacuated from the filter, the flow control valve is sealed properly, and that water levels meet normal standards.
