Follow these steps to properly set up your fishkeeper canister filter:
4.1. Preparing the Filter Media

- Rinse the activated carbon and bioceramic rings thoroughly under running water before placing them in the baskets to remove any dust or debris.
- Place the filled filter baskets back into the filter bucket.
- Align the cover's water inlet with the filter basket, then press it down and secure with the clasps.

4.2. Connecting Hoses and Pipes
- Set the flow valve on the filter head to the minimum position. Install the inlet and outlet nozzles into the top cover, press down the spanner to fix, and then set the flow valve to the maximum.
- Assemble the inlet and outlet pipes using the provided components.
- Attach the IN hose to the water inlet pipe and the OUT hose to the outlet pipe. Ensure all connections are tightened to prevent leaks.
- Install suction cups to the inlet and outlet pipes and fix them in suitable positions inside the fish tank.
4.3. Filter Placement and Priming
- Place the canister filter below the water level of your aquarium. For 35W/45W models, the height difference should be ≤180cm. For 18W/25W models, it should be ≤70cm.
- Ensure the PVC hoses are not twisted or kinked. If necessary, cut the hose length short to avoid interfering with operation.
- Press the air cell cover up and down repeatedly (3 to 6 times) to allow water to naturally flow into the canister until it is full. Do not turn on the power until the filter bucket is fully filled with water.
- Once the filter is primed and full of water, plug in the power cord. The filter will start operating.

Regular maintenance is crucial for the longevity and optimal performance of your fishkeeper canister filter. Follow these guidelines for cleaning and media replacement:
6.1. Rutinemæssig rengøring
- Before any maintenance, unplug the filter from the power outlet.
- Adjust the flow valve to the minimum setting, then remove the valve assembly from the filter head. This allows for routine cleaning and maintenance without disconnecting the water pipes from the aquarium.
- Open the lock clips and remove the filter head. Carefully lift out the filter baskets.
- Rinse mechanical filter media (sponges) under running tap water to remove trapped debris. Do not use soap or detergents.
- Clean the impeller and impeller housing in the filter head to ensure smooth operation.
- Reassemble the filter in reverse order, ensuring all seals are properly seated and clips are securely fastened.
6.2. Media Replacement
- Aktivt kul: Replace every 2-4 weeks, as its adsorptive capacity diminishes over time.
