Installation and Maintenance Recommendations:

Disconnect the Tidal 110 filter from its electrical power source before removing or replacing the pump. Carefully remove the original pump according to Seachem’s maintenance instructions and install the replacement unit securely in the designated housing.

Before restarting the filter, inspect the intake, pump chamber, and impeller area for accumulated debris or obstructions. Ensure all components are properly seated and the aquarium water level meets the filter’s minimum operating requirements.

Once installed, reconnect the power supply and confirm that water circulates normally through the filtration system.

For long-term reliability, periodically inspect and clean the pump and impeller assembly to prevent mineral deposits, algae buildup, and debris from interfering with operation.

Important Compatibility Information:

This replacement pump is intended for the Seachem Tidal 110 filter and should not be used as a replacement for the Tidal 35, 55, or 75 models. These filters use model-specific pump assemblies.
