Once installed and connected, plug in your pond pump (if separate) and then the filter unit. The filter will begin processing water. It may take several days for the pond water to become visibly clear, depending on its initial condition.
The filter features a multi-function switch on the top. This switch allows you to easily rotate and adjust the flow for normal filtration or to drain through both ports for cleaning or maintenance. Refer to the markings on the switch for 'CLEAN' and 'FILTER' positions.

The top of the lid includes a cleaning indicator. When the orange turbidity meter floats up, it indicates that the filter sponges require cleaning to maintain optimal performance.
Regular cleaning of the filter sponges is crucial for maintaining water quality. The VIVOGROW filter offers a convenient cleaning mechanism:

The built-in UV lamp purifies water as it passes through. The UV lamp has a limited lifespan and will need replacement periodically (typically every 8-12 months of continuous use). Refer to the product specifications for the correct replacement lamp type (13W UV-C). Disconnect power and follow the instructions for accessing and replacing the UV lamp, ensuring proper sealing upon reassembly.
| Problem | Possible Cause | Solution |
|---|---|---|
| Water not clearing | Clogged filter sponges; UV lamp not working; Pond size exceeds capacity; Insufficient pump flow. | Clean filter sponges; Check UV lamp (replace if needed); Verify pond size is within filter's capacity; Ensure pump flow matches filter requirements. |
| Water leakage | Loose hose connections; Damaged O-rings/gaskets; Cracked housing. | Tighten hose clamps; Inspect and replace O-rings/gaskets; Contact support if housing is cracked. |
| UV lamp not illuminating | Lamp burnt out; Faulty ballast; No power. | Replace UV lamp; Check power connection; Contact support if ballast is suspected. |
| Low water flow from filter | Clogged filter sponges; Inlet/outlet blocked; Pump issue. | Clean filter sponges thoroughly; Check for obstructions in hoses/ports; Inspect pond pump for proper operation. |
