How to use
Position the filter inside the aquarium according to the manufacturer's recommended waterline and secure it to the glass or wall using the provided suction mounts. Install the supplied filter media in the correct order as indicated in the product instructions. Connect to a power outlet with the aquarium running water covering the intake and prime the unit if required. Perform routine checks to ensure unobstructed flow and replace or clean filter media at intervals matched to the aquarium's bioload and water quality.
Usage recommendations
For reliable performance, inspect and clean the intake and impeller monthly and replace mechanical media more frequently in heavily stocked tanks. Maintain partial water changes and monitor water parameters regularly to support the biological filtration process. Avoid running the filter dry and follow safety instructions related to electrical equipment near water.
