5. Operating Instructions
Once installed, operating your VIVOGROW Bio Pressure Pond Filter is straightforward:
- Start Filtration: Ensure the function switch on the lid is set to the 'Filter' position. Turn on your pond pump. Water will flow from the pond, through the filter, and back into the pond, undergoing mechanical, biological, and UV-C purification.
- Monitor Cleaning Indicator: The orange turbidity meter on the lid will float up when the filter sponges require cleaning.
- Switching Modes: The top switch can be easily rotated to drain through both ports, allowing you to adjust the water flow or direct it for cleaning purposes.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your pond filter.
6.1. Cleaning Filter Sponges
When the orange cleaning indicator floats up, it's time to clean the filter sponges:
- Disconnect Power: Always turn off and unplug the pond pump and filter before cleaning.
- Activate Cleaning Mechanism: Rotate the function switch to the 'Clean' position. Turn the sponge cleaning handle several times to agitate and clean the filter sponges. This action dislodges accumulated debris.
- Drain Dirty Water: The dirty water will be expelled through the drainage port. Direct this water away from your pond, ideally to a garden area.
- Return to Filtration: Once the water runs clear, rotate the function switch back to the 'Filter' position. Reconnect power to resume normal operation.
