How to use
Turn off and unplug the Fluval FX6 filter and close any inlet/outlet valves before removing the existing lid. Carefully detach hoses from the current cover, remove the old lid following the manufacturer's service instructions, and inspect sealing gaskets for wear. Position the replacement lid onto the filter housing, ensuring an even fit and that sealing surfaces are clean.

Verify that seals are tight and check for leaks during initial operation.
Usage recommendations
Inspect and, if necessary, replace any O-rings or gaskets when changing the lid to ensure a reliable seal. Use the flow scale to make incremental adjustments and monitor water movement after each change. Regularly check for signs of wear or deformation on plastic mating surfaces and replace the cover if cracking or persistent leaks occur.
