Full details
The JBL CristalProfi e402 Greenline is a high-efficiency external canister filter designed for aquarists managing tanks between 40 and 120 litres.

FAQs
Can this filter be used in saltwater aquariums?
Yes, the JBL CristalProfi e402 is suitable for both freshwater and saltwater aquarium environments.
How often should I clean the media?
The pre-filter foam should be cleaned every 4–6 weeks, while the internal biological media only requires rinsing when flow is visibly restricted.
Does it come with filter media?
Yes, it arrives fully equipped with bio-filter balls and foam pads ready for installation.
Can I use it on a 150-litre tank?
The e402 is rated for 40-120 litres. It is recommended to use a larger model from the CristalProfi series for volumes exceeding 120 litres to maintain proper filtration cycles.
How do I ensure the filter doesn't leak during cleaning?
Always turn the patented safety valve to the closed position before disconnecting the hose block from the filter head.
Troubleshooting
Filter is making a rattling noise
Check the ceramic bearing and impeller for debris or air pockets trapped inside the pump head.
Water flow is significantly reduced
Check the intake strainer for blockages and ensure the pre-filter foam is not overly saturated with debris.
Unit will not prime
Ensure the output valve is open and that the filter is not placed too far below the aquarium level, which can strain the priming mechanism.
Pros and Cons
Pros
- Extremely energy efficient at only 4 watts

Cons
- Canister capacity is smaller than larger models, requiring regular pre-filter cleaning

Setup, Compatibility & Care
- Placement: Position the canister below the water level of your aquarium. For optimal performance, minimize the height difference between the filter and the tank.
- Media Prep: Rinse all included filter media with tank water (not tap water) to preserve beneficial bacteria before placing them in the baskets.
- Hose Connection: Attach the 12/16mm hoses firmly using the provided clips. Ensure the rotating connections are turned to the desired angle before locking the safety valve.
- Priming: Once connected, press the quick-priming button several times until the intake hose is full and the canister begins to draw water.
- Maintenance: Regularly rinse the large pre-filter foam every 4–6 weeks to keep the pump running efficiently. Clean the ceramic bearing periodically to prevent buildup and maintain silence.
